The correct answer is:
zero
Work done in displacement of charge, $\mathrm{W}=\mathrm{q} \Delta \mathrm{V}$
where $\Delta \mathrm{V}=$ potential difference between the displacement of charge Hence, work done in complete rotation is zero.
where $\Delta \mathrm{V}=$ potential difference between the displacement of charge Hence, work done in complete rotation is zero.
