A solid sphere of radius $R$ is charged uniformly. At what distance from its surface is the electrostatic potential half of the potential at the center

Options:

Answer:

Solution:

$V_{o u t s i d e} = \frac{1}{2} V_{centre}$

$\frac{k Q}{(R + h)} = \frac{1}{2} \times \frac{3}{2} \frac{K Q}{R}$

$R + h = \frac{4 R}{3}$

$h = \frac{R}{3}$
