Question

A surface will be an equipotential surface if (there may be more than one correct choice).A. the electric field is zero at all points on it.B. the electric field is tangent to the surface at all points.C. the electric field is perpendicular to the surface at all points.a. Ab. A, Bc. A, Cd. C

Answer 1

Answer:

c. A, C

Explanation:

On equi-potential surface, fields are equal in magnitude at all points . If field is zero at all points , they will be equal so first option is correct.

Field is perpendicular to  equipotential surface at all points.
