Which of the following is NOT the property of equipotential surface?

Options

A. They do not cross each other.
B. The rate of change of potential with distance on them is zero
C. For a uniform electric field they are concentric spheres.
D. They can be imaginary spheres

Answer

C

Explanation

Equipotential surfaces do not cross each other, also the potential gradient is zero, hence the word equipotential. Similarly these are imaginary surfaces. What is not correct is that they form concentric spheres but rather they are planes which are perpendicular to the electric field at that given point.
