A uniform electric field exists in x-y plane. The potential of points `A(2m,2m),B(-2m,2m)` and `C(2m,3m)` are `4V, 16V` and `12V` respectively. The electric field is

A

`(4hati+5hatj)V//m`

B

`(3hati+4hatj)V//m`

C

`-(3hati+4hatj)V//m`

D

`(3hati-4hatj)V//m`

Text Solution

Verified by Experts

The correct Answer is:
D
`E=E_xhati+E_yhatj`
Now we can use `intdV=-intE.dr`
two times and can find vales of `E_x and E_y`
