Shown in the figure are two point charges +Q and -Q inside the cavity of a 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 : [Main 10 April 2015]

Correct Answer is : σ1=0,Q1=0σ2=0,Q2=0

\sigma_1\neq0,Q_1\neq0 \sigma_2\neq0,Q_2\neq0

\sigma_1\neq0,Q_1=0 \sigma_2\neq0,Q_2=0

\sigma_1\neq0,Q_1=0 \sigma_2=0,Q_2=0

\sigma_1=0,Q_1=0 \sigma_2=0,Q_2=0

Shown in the figure are two point charges +Q and −Q inside the cavity of a spherical shell. The charges are kept near the surface of the cavity on opposite sides of the centre of the shell. If σ1 is the surface charge on the inner surface and Q1 net charge on it and σ2 the surface charge on the outer surface and Q2 net charge on it then :
