Show in the figure are two point charge + Q and - Q inside the cavity of the Spherical .shell the changes 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 :

A solid spherical conductor of radius R has a spherical cavity of radius at its centre. A charge is kept at the centre. The charge at the inner surface, outer surface are respectively.

If a charge – 150 nC is given to a concentric spherical shell and a charge +50 nC is placed at its centre then the charge on inner and outer surface of the shell is

Is the force of interaction between two points charges affected due to the presence to another charge?
