Question

Electric potential ‘V’ at a distance ‘r’ from a point charge is directly proportional to ______.

Options

• r

• r²

• `1/r`

• `1/r^2`

Answer 1

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`
