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

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

B

Zero

C

`-1/(4pi epsilon_(0))q/r`

D

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

Text Solution

Verified by Experts

The correct Answer is:
B
`W=q(V_(A)-V_(B))=qxx0(V_(A)=V_(B)," equipoten-tial")`
