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?
