Show in the figure are two point charge + Q and - Q inside the cavity of the Spherical shell. the charges are kept near the surface of the cavity on opposite sides of the centre of the shell. if `sigma_1` is the surface charge on the inner surface and `Q_1` net charge on it and `sigma_2` the surface charge on the outer surface and `Q_2` net charge on it then :

Options

A. `sigma_1 = 0 , Q_1 = 0 , sigma_2 = 0 , Q_2 =0`
B. `sigma_1 ne 0 , Q_1 = 0 , sigma_2 ne 0 , Q_2 =0`
C. `sigma_1 ne 0 , Q_1 ne 0 , sigma_2 ne 0 , Q_2 ne0`
D. `sigma_1 ne 0 , Q_1 = 0 , sigma_2 = 0 , Q_2 =0`

Answer

D
