A charge Q placed at the centre of a m etallic spherical shell w ith in n er and outer radii `R_(1)` and `R_(2)` respectively. The norm al com ponent of the electric field at any point on the Gaussian surface w ith radius between `R_(1)` and `R_(2)` will be

Options

A. zero
B. `(Q)/(4piR_(1)^(2))`
C. `(Q)/(4pi(R_(1)-R_(2))^(2)`
D. `(Q)/(4pi(R_(2)-R_(1))^(2)`

Answer

A

Explanation

The induced charges will appear at the inner and outer surface of the metallic spherical shell. Also there is no charge in between the metal of the shell. So, the normal component of the electric field at any point on the Gaussian surface with radius between and will be zero.
