Q.
The given graph shows variation (with distance r from centre) of :
JEE MainJEE Main 2019Electrostatic Potential and Capacitance
Solution:
F or a spherical shell of radius
$r _{0}$
$$
\begin{array}{ll}
V & =\frac{ KQ }{ r _{0}} & \text { for } x < r _{0} \\
V & =\frac{ KQ }{ x } & \text { for } x > r
\end{array}
$$
$\therefore $ this graph is for uniformly charged spherical shell
