A point positive charge of Q' units is moved round another point positive charge of Q units in circular path. If the radius of the circle r is the work done on the charge Q' in making one complete revolution i-

A

`Q/(4 pe_(0)r)`

B

`(Q Q')/(4 pe_(0)r)`

C

Zero

D

`(Q')/(4 pe_(0)r)`

Text Solution

Verified by Experts

The correct Answer is:
C
