Electric field inside material of conductor is zero.

Q. As shown in the figure, a point charge $Q$ is placed at the centre of conducting spherical shell of inner radius $a$ and outer radius $b$ . The electric field due to charge $Q$ in three different regions I, II and III is given by:
(I: $r < a$ , II: $a < r < b$ , III: $r > b)$

$E_{I} = 0, E_{II} = 0, E_{III} = 0$

$E_{I} \neq = 0, E_{II} = 0, E_{II} = 0$

$E_{I} = 0, E_{II} = 0, E_{III} \neq = 0$

$E_{I} \neq = 0, E_{II} = 0, E_{III} \neq = 0$
