If a charged particle moves along a path for which its displacement at each point is perpendicular to the electric field at that point, then its potential energy remains constant on that path.

Question

Quizplus · Accepted Answer

The electric potential energy of a charged particle depends on its position relative to the electric field. If the displacement of the particle is always perpendicular to the electric field, it means the particle is moving along an equipotential surface where the electric potential (and thus potential energy) remains constant.
