प्रश्न
A charge 'q' is moved from a point A above a dipole of dipole moment 'p' to a point B below the dipole in equatorial plane without acceleration. Find the work done in the process.

उत्तर
The net force on the charge q is directed parallel to the dipole and hence perpendicular to its motion along AB.
∴ Work done = 0
