I've been trying and trying to do this problem for quite a while now, and I can't seem to get an answer which agrees with the book.

I figured that one metal sphere would then end up with a charge of 10^13 electrons (so I multiplied that by 1.60x10^-19 to get the charge of all the electrons in the sphere). But there is no charge given for the second sphere! I was using the equation:In a charging process, 10^13 electrons are removed from a metal sphere and placed on a second sphere that is initially uncharged. Then the electrical potential energy associated with the two spheres is found to be 7.2x10^-2 Joules. What is the distance between the two spheres?

Nothing seems to work. Even using the same value for q1 and q1 doesn't produce the correct answer, wich the book feels is(q1*q1/r)Coloumb Constant (8.99*10^9) = Energy

**0.32 meters**.

I'm stuck... thanks so much for any help!
