Problem
A neutral metal sphere is placed near (but does not touch) a negatively charged rod. While the rod remains nearby, the sphere is momentarily connected to ground by a wire that is then removed before the rod is taken away. Describe the final net charge on the sphere and briefly explain how grounding produces that result.
