There is a charge of `10 mu C` at the centre of a circle of radius 10m. The work done is moving a unit positive charge once around the circle is

A

0

B

100 J

C

10 J

D

150 J

Text Solution

Verified by Experts

The correct Answer is:
A
Hint: `W = q Delta V`
Here, `Delta V = 0` because all the points on the circumference are at the same distance from the centre. So potential remains the same.
