उत्तर
Electric potential ‘V’ at a distance ‘r’ from a point charge is directly proportional to `bb\underline(1/r)`.
Explanation:
`V = (kQ)/r`
Where k is Coulomb’s constant, Q is the charge and r is the distance from the charge.
From this equation, we can see that V is directly proportional to `1/r`
