Behaviour of Metallic Conductors in electric field

                                                               figure (a)

• The net electric field inside a charged conductor is zero i.e., no electric lines of force exist inside the conductor
• The net charge inside a charged conductor is zero.
• The electric field (i.e., electric lines of force) on the surface of a charged conductor is perpendicular to the surface of the conductor at every point
• The magnitude of electric field just outside a charged conductor is σ/ε_o where σ is the surface charge density.
• The electric potential is the same (i.e., constant) at the surface and inside a charged conductor Inside a charged conductor, E = 0

   Now                          

This means that V is constant.
