(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two uncharged metal spheres, spaced 15.0 cm apart , have a capacitance of 24.0 pF. How much work would it take to move 12.0 nC of charge from one sphere to the other?

2. Relevant equations

V = Q/[4(pi)eor]

(delta)K + (delta)U = 0 *I think

3. The attempt at a solution

I'm not quite sure how to do this problem. I think I would first have to find out the potential difference between the spheres?

V = Q/[4(pi)eo*r]

=(12.0 x 10^-9)/[4(pi)(8.85 x 10^-12)(1.5 x 10^-1)

=719 V

Can somebody please tell me if I'm going in the right direction and, if not, could you please steer me in the right direction?
