The potential at a point x ( measured in `mu` m) due to some charges situated on the x-axis is given by
`V(x)=20//(x^2-4) vol t`

A

5/3 volt/`mu`m and in the –ve x direction

B

5/3 volt/`mu`m and in the +ve x direction

C

10/9 volt/`mu`m and in the –ve x direction

D

10/9 volt/`mu`m and in the +ve x direction

Text Solution

Verified by Experts

The correct Answer is:
D
`E=-"dv"/"dx"=20/((x^2-4)^2) (2x) = 10/9`
