The work done in bringing a unit positive charge from infinite distance to a point at distance x from a positive charge Q is W. Then the potential `phi` at that point is

A

`(WQ)/(d)`

B

`W/d`

C

`W`

D

`WQ`

Text Solution

Verified by Experts

The correct Answer is:
c
The work done in bringing a unit positive charge from infinity to a point which is at a distance d from the positive charge Q is defined as the potential at the given point due to the charge Q. Therefore, potential at that point is W.
