All rights reserved. Differentiate between conductors and insulators. Distinguish between charging by contact, charging by induction, and charging by polarization. Friction Rods Electrons from animal fur are transferred to atoms in ebonite hard rubber. Ebonite acquires a net excess of electrons. Electrons from a glass rod will transfer to a silk cloth and give rise to an excess of electrons on the silk. Your hair becomes positively charged when you rub a balloon across it. Electric charge is conserved. The amount of positive charge acquired by your hair equals the amount of negative charge acquired by the balloon.

That is, when an object is charged, its charge is always a multiple of a fundamental unit of charge. Most metals are conductors. An electrical insulator, or nonconductor, is a material in which charges cannot move freely. Electrons are tightly bound to the atom. Nonmetallic materials, such as glass, rubber, and wood are good insulators. Conductors can be charged by induction. Induction is a process of charging a conductor by bringing it near another charged object and grounding the conductor. With polarization, the charges within individual molecules are realigned such that the molecule has a slight charge separation. Compare electric force with gravitational force. Apply the superposition principle to find the resultant force on a charge and to find the position at which the net force on a charge is zero. When the charges q 1 and q 2 are alike they repel each other, and when they are opposite they attract each other. The resultant force on a charge is the vector sum of the individual forces on that charge.

Adding forces this way is an example of the principle of superposition. When a body is in equilibrium, the net external force acting on that body is zero. A charged particle can be positioned such that the net electric force on the charge is zero. Find the magnitude and direction of the resultant force on q 3. Define the problem, and identify the known variables. ResourcesChapter menu Chapter 16 Section 2 Electric Force Sample Problem, continued The Superposition Principle Tip: According to the superposition principle, the resultant force on the charge q 3 is the vector sum of the forces exerted by q 1 and q 2 on q 3. First, find the force exerted on q 3 by each, and then add these two forces together vectorially to get the resultant force on q 3. Determine the direction of the forces by analyzing the charges. The force F 3,1 is repulsive because q 1 and q 3 have the same sign.

The force F 3,2 is attractive because q 2 and q 3 have opposite signs. Find the x and y components of each force. At this point, the direction each component must be taken into account. Calculate the magnitude of the total force acting in both directions. Use the Pythagorean theorem to find the magni- tude of the resultant force. Use a suitable trigonometric function to find the direction of the resultant force. A field force is a force that is exerted by one object on another even though there is no physical contact between the two objects. Gravitational attraction is also a field force. Draw and interpret electric field lines. Identify the four properties associated with a conductor in electrostatic equilibrium. ResourcesChapter menu Chapter 16 Section 3 The Electric Field Electric Field Strength Intensity An electric field is a region where an electric force on a test charge small positive charge can be detected. Q exerts an electric field on q 0. An electric field exists in the region around a charged object.

When q is - the electric field is directed toward q. The electric field is zero everywhere inside the conductor otherwise charges would move and it would not be at equilibrium. On an irregularly shaped conductor, charge tends to accumulate where the radius of curvature of the surface is smallest, that is, at sharp points. Find the electric field strength at point P,which is on the y-axis 0. You must first calculate the electric field produced by each charge individually at point P and then add these fields together as vectors. Calculate the electric field strength produced by each charge. Because we are finding the magnitude of the electric field, we can neglect the sign of each charge.

Analyze the signs of the charges. The field vector E 1 at P due to q 1 is directed vertically upward, as shown in the figure, because q 1 is positive. Likewise, the field vector E 2 at P due to q 2 is directed toward q 2 because q 2 is negative. Find the x and y components of each electric field vector. Calculate the total electric field strength in both directions. Use the Pythagorean theorem to find the magnitude of the resultant electric field strength vector. Use a suitable trigonometric function to find the direction of the resultant electric field strength vector. Evaluate your answer. The electric field at point P is pointing away from the charge q 1, as expected, because q 1 is a positive charge and is larger than the negative charge q 2.

Problem 56 Video Transcript So we have an arrangement of three charges here. Two of them are positive shown by the red charge, and then one of them is negative shown by the blue. And we'll call them 12 and three just in order from left to right. And the first thing that we can do is we can look at what the electric field is at a particular point. The point doesn't have to be at where one of the charges we can pick any point, really. But let's pick this point here with a purple DOT is, we can find the Net electric field just by adding, that's what this symbol means here. Take the sum of all the electric fields at each from each one of those charges. So the electric field, due to charge one, the electric field due to Charge two and the electric field due to charge three. Um, so we'll call these 12 and three and we'll find the electric field there.

So let's start by, um, looking at e one e one is going to equal K times Q one divided by r one squared, where R is the separation between each of these now each block here is one centimeter, so that's a two centimeter distance. Remember, we need to plug everything in terms of meters. So K is nine times 10 to the nine. The first charge there is 6. That's micro columns. We have to convert that to cool ums by making it times 10 and negative six. And then that's divided by the separation distance squared, which is point zero to squared. When I put this into the calculator, we do nine times 10 and 96 times 10 to the negative six. And then we divide that by And what I get for E one is, um, a really big number. So I'm gonna write it out first, and we'll put in scientific notation afterwards and then six zeros after that. So that's going to be 1. So eight Newtons per Coolum. So that's E one. And the other thing before we move on to eat, too, is we want to determine whether it's going to be in the positive direction or the negative direction.

So the way that we do that is where this purple point is. We put a positive test charge. Then we ask ourselves, How would that charge be pushed based on Charge one? So because Charge one is positive and my test charges positive, they're going to repel. So this is actually going to feel of force to the right. So that means that this is going to be a positive electric field. Let's continue with E to. It's going to be K Times Q two over our two squared. So that's nine times 10 to the nine. Q two is 1. And here is just one centimeter. So that's gonna be We're gonna punch this in the calculator, and then we get actually the same value, it seems, um so e to is equal to the same number.

That's interesting. And again, we have to ask ourselves, which direction would this thing be pushed now? Because it's to the right of it. This positive test charges actually gonna be pushed in the opposite direction. So this is actually going to turn out to be a negative field because it's we're just saying relative to where the position is.

It's pointing to the left, so that's why we're calling it negative. Um, so far, those two fields are actually canceling each other out. So let's look at E three. E three is going to be K, which is nine times 10 to the nine times Q three, which is negative two times 10 to the negative six. And then that's divided by the distance for that one, which is another three centimeters. So that's gonna be three squared. So we put that into the calculator, and then we get negative, too, and then a bunch of zeros.

Let's count seven zeros right that I get that. Okay, so seven zeros, which is gonna be negative 2. If I put a positive test charge here and have a negative, it's going to be attracted to that. So actually, this is gonna end up being a positive value just because it's going to the right. So now that I have all three, I add them up. But this is super easy, because when I do, um, you know, so Net electric field is e one plus e two plus e three. You want to need to are the same. So there's gonna cancel out. So it's just gonna equal whatever e three is, which is, um, two times 10 to the seven Newton's problem.
