Question

Consider the two points, A and B, and a path connecting them, as shown. Let VA be the electric potential at point A, and let VB be the electric potential at point B. Choose all of the following statements that are true. If none are true, write "none."

A. If VA=VB, then the electric field will do no work on a charged particle that moves along the path from A to B.

B. If VA=VB, then the path must be part of an equipotential surface.

C. If the electric field is perpendicular to the path everywhere along the path, then VA=VB.

D. If VA=VB, then the electric field must be zero everywhere along the path.

E. If VA=VB, then the electric field at A must equal the electric field at B (although is might vary along the path).

Explanation / Answer

C. If the electric field is perpendicular to the path everywhere along the path, then VA=VB.
