`2q` and `3q` are two charges separated by a distance `12cm` on x-axis .A third charge `q` is placed at `5cm` on `y-axis` as shown in figure .Find the change in potential energy of the system if `3q` is moved from initial position to a point on `X-axis` in circular path

A

`(q^(2))/(4piepsilon_(0))`

B

`(6q^(2))/(4piepsilon_(0)91)`

C

`(18q^(2))/(4piepsilon_(0)91)`

D

`(3q^(2))/(4piepsilon_(0))`

Text Solution

Verified by Experts

The correct Answer is:
3

force of interation
`=(2pq)/(4piepsilon_(0))[(1)/((d-l)^(3))-(1)/((d+l)^(3))]`
