Q. The variation of electrostatic potential with radial distance $r$ from the centre of a positively charged metallic thin shell of radius $R$ is given by the graph

NEETNEET 2020Electrostatic Potential and Capacitance

Solution:

$V_{\text{in}} = V_{s}=\frac{KQ}{R}$ and
$V_{\text{out}} = \frac{KQ}{r} (r >\, R)$
