Question

The work done in moving a point charge of $ 10 \mu \mathrm{C} $ through a distance of $ 3 \mathrm{~cm} $ along the equatorial axis of an electric dipole is, zero, $ 30 \times 10^{-6} \mathrm{~J} $, $ 20 \times 10^{-6} \mathrm{~J} $, $ 5 \times 10^{-6} \mathrm{~J} $

MARKS App · Accepted Answer

The electric potential difference along the equatorial axis of an electric dipole is zero. The change of potential energy stored in charge 10 μC is equal to the work done on 10 μC to bring it from A to B . ∴ W = q ∆ V = 0
