Question

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.

Solution
Verified by Toppr

Work done in the process is zero.

It is because , equatorial plane of a dipole is equipotential surface and work

done in moving charge on equipotential surface is zero.
W=qVAB=q×O=0
