1. The problem statement, all variables and given/known data What is the electrostatic potential energy of an isolated spherical conductor of radius 24 cm that is charged to 3.9 kV? 2. Relevant equations Electric potential U = (kQ)/r 3. The attempt at a solution U = ((8.99 * 109 ) * (3.9 * 103)/(0.24) Could someone walk me through how to do this? Its a simple problem I know...but i'm not understanding it, thanks!
