What is the total work done on moving a test charge on an equipotential surface?

(a) Maximum

(b) Minimum

(c) Constant

(d) Zero

This question was addressed to me by my college director while I was bunking the class.

The origin of the question is Electrostatics of Conductors in chapter Electrostatic Potential and Capacitance of Physics – Class 12

Correct answer is (d) Zero

The explanation is: The potential difference between any two points on an equipotential surface is zero.

Work done=Test charge x potential difference(0)

=Zero .
