Why is there no work done in moving a charge from one point to another on an equipotential surface?

Answer»

The potential difference between any two points of equipotential surface is zero.

We have

V₁ - V₂ = \(\cfrac{W}q\) = 0 ⇒ W = 0

Therefore, the work done in moving a charge on an equipotential surface is zero.
