On rotating a point charge g around a charge Q in a circle of radius r, the work done is

A

`q. 2 pi r`

B

`(q. 2pi O)/r`

C

zero

D

`Q/(2 epsi_0 r)`

Text Solution

Verified by Experts

The correct Answer is:
C
Work done is zero because circle of radius r around a charge +Q behaves as an equipotential surface.
