Suppose you touch a negatively charged object to a metal sphere so that electrons move from the charged object onto the sphere. After far separation of the charged object and the sphere, the electrons on the sphere will be
located at the place where the charged object was.
distributed in small bunches over the sphere's surface.
distributed evenly over the sphere's surface.
pulled off the sphere along with the charged object.
