Question

The value of electric potential at a distance r from a point charge will be
(A)
inversely proportional to r
proportional to r
(B)
(C)
(D)
inversely proportional to p2
proportional to r2​

Answer 1

Answer:

The electrostatic potential due to a point charge varies as inversely proportional to the distance of the charge. It is represented as:

V∝

r
