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)
Select the correct option:
A
$E_1=0, E_{11}=0, E_{111 \neq 0}$
B
$E_1 \neq 0, E_{11}=0, E_{111} \neq 0$
C
$E_1 \neq 0, E_{11}=0, E_{111}=0$
D
$E_1=0, E_{11}=0, E_{111}=0$
✓ Correct! Well done.
