The work done in bringing 5 C of charge...

The work done in bringing 5 C of charge from infinity to a point A near a charged body is 20 J. Find the potential at point A.

Text Solution

Verified by Experts

Given charge `q = 5C`
Work done, `w = 20 J`
`:.` The electric potential `V = (w)/(q) = (20 J)/(5 C) = 4 V`
