1. The problem statement, all variables and given/known data A large hollow metallic sphere A is charged positively to a potential of 100 V and a small sphere B to a potential of 50 V. Now B is placed inside A and they are connected by a wire. In which direction will the charge flow? 2. Relevant equations 3. The attempt at a solution A is at a higher potential, B at a lower potential. So charge should flow from A to B? Even if the potentials alter due to the placement of B inside A, A is still at a higher potential? I don't know the answer, so please confirm?
