The work done in carrying a charge 'a' once round a circle of radius 'a' with a charge Q at its centre is

A

`(Q_(1)Q_(2))/(4piepsilon_(0)R^(2))`

B

zero

C

`(Q_(1)Q_(2))/(4piepsilon_(0)R)`

D

infinite

Text Solution

Verified by Experts

The correct Answer is:
b
The electric field is conservative. Therefore, no work is done in moving a charge around a closed path in a electric field
