The electrostatic potential on the surface of uniformly charged spherical shell of radius $R = 10 cm$ is 120 V. The potential at the centre of shell, at a distance $r = 5 cm$ from centre, and at a distance $r = 15 cm$ from the centre of the shell respectively, are :

Options:

Answer:

Solution:

Potential inside shell is equal to potential on surface
$V_{in} = V_{surface} = \frac{kQ}{R} = 120 V$
at $r = 15 cm$
$V = \frac{kQ}{r} = \frac{120 \times 10}{15} = 80 V$
