Question
Equipotential surfaces are 5 cm apart from each other. How much work will be required to move a 500 µC charge between distant points?
✓

Answer

Potential difference between any two points on the post-isopotential surface $\Delta V =$ zero
Therefore work $W =$ charge $q \times$ potential difference $(\Delta V )$$=100 \mu C \times 0=\text { zero }$
i.e, no work has to be done.
