An equipotential surface is a surface where the electric potential is the same at every point. The potential difference ($\Delta V$) between any two points on an equipotential surface is zero. The work done ($W$) in moving a charge ($q$) between two points is given by the formula $W = q \Delta V$. If $\Delta V = 0$, then $W = q \times 0 = 0$.
The work done in moving a positive charge on an equipotential surface is (i) Finite (ii) Positive (iii) Negative (iv) Zero
