There are two equipotential surafce as shown in figure. The distance between them is `r`. The charged of `-q` coulomb is taken from the surface A to B, the resultant work done will be

A

`W = (1)/(4pi epsilon_(0)) (q)/(r )`

B

`W = (1)/(4pi epsilon_(0)) (q)/(r^(2))`

C

`W = -(1)/(4pi epsilon_(0)) (q)/(r^(2))`

D

`W =` zero

Text Solution

Verified by Experts

The correct Answer is:
D
The work done is given by `= q (V_(2) - V_(1)) = 0`
