A thin metallic spherical shell contains a charge Q on it. A point charge q is placed at the center of the shell and another charge q1 is placed outside it as shown in the figure. All the three charges are positive. Find the force on the charge

Charge q on a small conducting sphere S1 is placed inside a large hollow metallic sphere S2 having a charge Q as shown in figure. The sphere is connected to shell by a conducting wire. The charge on S1 will then be

A positive charge Q is placed at the centre O of a thin metallic spherical shell. Select the correct statements from the following: (i) The electric field at any point outside the shell is zero (ii) The electrostatic potential at any point outside the shell is Q/4πε0r , where r is the distance of the point from O (iii) The outer surface of the spherical shell is an equipotential surface (iv) The electric field at any point inside the shell , other than O , is zero

A point charge +Q is placed at point B at a distance 2R from the center O of an uncharged thin conducting shell of radius R as shown in figure. If VA be the potential at point A, which is at a radial distance of R/2 from the center of the shell, then
