As shown in the figure, a point charge $\displaystyle Q$ is placed at the centre of conducting spherical shell of inner radius $\displaystyle a$ and outer radius $\displaystyle b$. The electric field due to charge Q in three different regions I, II and III is given by:
(I : $\displaystyle r<a$, II : $\displaystyle a<r<b$, III: $\displaystyle r>b$ )
Official answer
From NTA’s final answer key for this paper.
