Re: equipotentials

If equipotential surfaces crossed, then a test charge +q would simultaneously
have two different energy levels (taking potential as the amount of energy
per charge) at their union loci. Even Schrödinger's cat might feel uncertain
about such a situation.

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

(This is another disagreement between me and the "back of the book" answer
for a textbook question)
