Vedclass · Answer

(D) The electric potential at a point $P$ inside a spherical shell is the sum of the potential due to the charge $Q$ at the centre and the potential due to the charge $q$ on the shell.$1$. Potential due to charge $Q$ at distance $r = R/2$ is $V_Q = \frac{1}{4\pi \epsilon_0} \frac{Q}{R/2} = \frac{2Q}{4\pi \epsilon_0 R}$.$2$. Potential due to charge $q$ on the shell at any point inside the shell (including the centre) is constant and equal to the potential at the surface: $V_q = \frac{1}{4\pi \epsilon_0} \frac{q}{R}$.$3$. Total potential at point $P$ is $V = V_Q + V_q = \frac{2Q}{4\pi \epsilon_0 R} + \frac{q}{4\pi \epsilon_0 R}$.

$A$ thin spherical conducting shell of radius $R$ has a charge $q$. Another charge $Q$ is placed at the centre of the shell. The electrostatic potential at a point $P$ at a distance $R/2$ from the centre of the shell is
