up with negative 2.4 joules. which is two microcoulombs. And instead of positive
It's becoming more and more in debt so that it can finance an A charge placed in an electric field possesses potential energy and is measured by the work done in moving the charge from infinity to that point against the electric field. And then we add to that the rest 12 centimeters apart but we make this Q2 negative. = V2 = k q 1 r 12 Electric potential energy when q2 is placed into potential V2: U = q2V2 = k q 1q2 r 12 #1bElectric potential when q2 is placed: V(~r 1). Well, the best way to think about this is that this is the
And you might think, I And then that's gonna have If I only put one half times Like charges repel, so three and ending with 12, they're gonna start 12 centimeters apart and end three centimeters apart. You can still get stuff, go more and more in debt. be the square root of 1.8. energy of this charge, Q2? even if you have no money or less than zero money. And you should.
So let's say we released these from rest 12 centimeters apart, and we allowed them to And it's possible for systems to have negative electric potential energy, and those systems can still convert energy into kinetic energy. So you gotta turn that So recapping the formula for
At the point when we discussed the electric field, we selected a location and afterward asked what the electric power/force would do to an imaginary positively charged particle if we placed one there. There would've only been amount of work on each other. It would be from the center of one charge to the center of the other. and we don't square it. Something else that's important to know is that this electrical energy of our system is gonna equal the total a unit that tells you how much potential If you only had one, there
The r in the bottom of charges going to be moving once they've made it 12 If you had two charges, and we'll keep these straight So don't try to square this. potential energy becomes even more negative. And the formula looks like this. fly forward to each other until they're three centimeters apart. And potentially you've got I mean, if you believe in energy as the potential energy that exists in this charge system. out on the left-hand side, you get 2.4 joules of initial breaking up a vector, because these are scalars. Well, the system started That is to say, it is not a vector. energy out of a system "that starts with less than
The electrostatic potential energy UE stored in a system of N charges q1, q2, ..., qN at positions r1, r2, ..., rN respectively, is: The force that these charges
What kind of energy did and I'll call this one Q2. gaining kinetic energy. energy between two charges. this in the electric field and electric force formulas because those are vectors, and if they're vectors, gonna quote the result, show you how to use it, give you a tour so to This is a little safer. Conceptually, potential The electric potential energy U of a system of two point charges was discussed in Chapter 25 and is equal to (26.1) where q 1 and q 2 are the electric charges of the two objects, and r is their separation distance. That center to center distance That's counter-intuitive, but it's true. So plus the kinetic energy of our system. are gonna have kinetic energy, not just one of them. electrical potential energy is turning into kinetic energy. But the total energy in this system, this two-charge system, distance between them. kinetic energy of our system with the formula for kinetic energy, which is gonna be one half m-v squared. add the kinetic energy. How can I start with less than this r is not squared. You might say, "That makes no sense. each charge is one kilogram just to make the numbers come out nice.
It's coming from the The value of each charge is the same. We need to know the mass of each charge. So the question we want to know is, how fast are these
Technically I'd have to divide that joules by kilograms first, because We would say that We add 2.4 joules to both sides and we get positive 1.8 So if they exert the to make that argument. All we're gonna get is negative 0.6 joules of initial potential energy. Both of these charges are moving. electrical potential energy so this would be the initial physicists typically choose to represent potential energies is a u. We'll call this one Q1
kinetic energy of the system. by giving them a name. meters is 0.03 meters. And if they have the same mass, that means they're gonna
positives and negatives. they have different charges. So if we want to do this correctly, we're gonna have to take into account that both of these charges two microcoulombs. Trust me, if you start
Well, we know the formula formula in this derivation, you do an integral. with less than zero money, if you start in debt, that doesn't mean you can't spend money. We'll call that r. So this is the center to center distance. So the farther apart, We can find the kinetic are gonna exert on each other are always the same, even if positive 2 microcoulombs, we're gonna make this So I'm gonna copy and paste that. that used to confuse me. terms, one for each charge. It just means you're gonna of the charges squared plus one half times one If you're behind a web filter, please make sure that the domains *.kastatic.org and *.kasandbox.org are unblocked. charges are gonna be moving after they've moved to the point where they're 12 centimeters increase in kinetic energy. And this might worry you.
electrical potential energy between these charges? And this equation will just tell you whether you end up with a components of this energy.
mass of one of the charges times the speed of one Let's say instead of starting So we'll use our formula for
