Question

What is an equipotential surface? Why two equipotential surfaces cannot
intersect?

Answer 1

Answer:

They cannot intersect each other because two different equipotential surface have different electric potential, so if they intersect then the point of intersection will have twodifferent potentials at the same point which is not possible. Because electric field lines can't point to two directions at the same point.

Answer 2

.The surface, the locus of all points at the same potential, is known as the equipotential surface. No work is required to move a charge from one point to another on the equipotential surface. In other words, any surface with the same electric potential at every point is termed as an equipotential surface.
