Question

An electric field is directed along the tangent of an equipotential surface.

(a) True

(b) False

I had been asked this question in an internship interview.

The above asked question is from Equipotential Surfaces in chapter Electrostatic Potential and Capacitance of Physics – Class 12

Answer 1

Correct choice is (b) False

The explanation is: Electric field lines cut the equipotential surfaces at an angle of 90 degrees. The direction of the electric field is the same as the direction of electric field lines. Therefore, the field is perpendicular to the equipotential points, not tangent to them.
