A charge 'q' ...

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.

Open in App

Solution

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.
$W = q V_{A B} = q \times O = 0$
