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 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

equipotential lines are shown. In the following figure
