If a unit charge is taken from one point to another point over an equipotential surface, then (a) work is done on the charge. (b) work is done by the charge. (c) work done on the charge is constantly increasing. (d) work done to move a charge is zero.

Answer: (d). All points on an equipotential surface have the same potential, Δ V = 0. W = q Δ V = 0 So the answer is (d) work done to move a charge is zero.

Electric Potential & Equipotentials

If a unit charge is taken from one point to another point over an equipotential surface, then

Show answer and solution

Answer: (d)

All points on an equipotential surface have the same potential, $\Delta V = 0$ .
$W = q\,\Delta V = 0$
So the answer is (d) work done to move a charge is zero.
