Electric Potential
Potential at distance r from point charge q (zero at infinity) is:
Select the correct option:
Solution
k q / r
Electric Potential (V) at a point is the work done per unit charge in bringing a positive test charge from infinity to that point.
- For a point charge q at distance r: V=rkq=4πϵ01rq
- Note: V is a scalar quantity. It depends on the sign of q.
