Question

A charge $Q$ placed at the center of a metallic spherical shell with inner and outer radii $R_1$ and $R_2$ respectively. The normal component of the electric field at any point on the Gaussian surface with radius between $R_1$ and $R_2$ will be

• A. zero
• B. $\dfrac{Q}{4\pi R_1^2}$
• C. $\dfrac{Q}{4\pi R_2^2}$
• D. $\dfrac{Q}{4\pi (R_1 - R_2)^2}$
• E. $\dfrac{Q}{4\pi (R_2 - R_1)^2}$

Hint:

Electric field inside any conductor in electrostatic equilibrium is always zero.
