A charge +q is placed at the centre of a dotted circle. Work done in taking charge + q from A to B is `W_(1)` and B to C is `W_(2)`. Then:

A

`W_(1)gtW_(2)`

B

`W_(1)ltW_(2)`

C

`W_(1)=W_(2)`

D

`W_(1)neW_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`W_(1)=W_(2)`
Explanation: A, C and B are at same distance from the centre. So, the potential at all these 3 points will be same because work done, `W_(1), W_(2)` should be zero because the potential difference is zero.
So, `W_(1)=W_(2)`
