Question

Electric potential of uniformly charged solid sphere at its surface

• A. increases with increase in radius
• B. decreases with increase in radius
• C. remains constant
• D. none of the above

Answer 1

The correct option is B decreases with increase in radius

Electric potential at the surface of solid charged sphere is given by

$v=\frac{Q}{4\pi {ϵ}_{o}R}$

$⟹v\propto \frac{1}{R}$

Hence, potential difference decreases with increase in radius.

Answer-(B)
