Q. The electrostatic potential of a uniformly charged thin spherical shell of charge $Q$ and radius $R$ at a distance $r$ from the centre is
A) $\frac{Q}{4\pi\varepsilon_{0}r}$ for points outside and $\frac{Q}{4\pi\varepsilon_{0}R}$ for points inside the shell
B) $\frac{Q}{4\pi\varepsilon_{0}r}$ for both points inside and outside the shell
C) Zero for point outside and $\frac{Q}{4\pi\varepsilon_{0}r}$ for points inside the shell
D) Zero for both points inside and outside the shell
Explanation
The correct answer is Option A: $\frac{Q}{4\pi\varepsilon_{0}r}$ for points outside and $\frac{Q}{4\pi\varepsilon_{0}R}$ for points inside the shell.
