Problem
A neutral metal sphere rests on an insulating stand. A negatively charged rod is held near the sphere without touching it. While the rod is in place, the sphere is grounded by touching it briefly with a finger. After removing your finger and then taking the rod far away, describe the net charge that remains on the sphere and explain your reasoning in one or two sentences.
