Consider a collection of charges in a given region and suppose all other charges are distant and have a negligible effect. Further, the electric potential is taken to be zero at infinity. If the electric potential at a given point in the region is zero, which of the following statements must be true? The electric field is zero at that point. The charges have the same sign and are symmetrically arranged around the given point.     The electric potential energy is a minimum at that point. There is no net charge in the region.
