Subject: equipotentials


Can equipotential surfaces cross? If so then in what direction does the electric field
point at the line of intersection?

Short answer, no. Else they would represent a weird kink in a single equipotential surface. Such a kink would not be differentiable, so no gradient could be defined, hence no electric field vector.
