A charge Q is uniformly distributed over a large plastic plate. The electric field at a point P close to the centre of the plate is `10V m^(-1)`. If the plastic plate is replaced by a copper plate of the same geometrical dimension and carryin the same charge `Q_1` the electric field at the point P will become

A charge q is uniformly distributed over a large plastic plate. The electric field at a point P close to the centre and just above the surface of the plate is 50 V/m. If the plastic plate is replaced by a copper plate of the same geometrical dimensions and carrying the same uniform charge q, the electric field at the point P will become :

A charge Q is uniformly distributed over one large insulating surface and field intensity at a point X near its centre E. If it were a metal plate in place of an insulating surface then the electric field intensity at point X will become

Three large plates having uniform surface charge densities are shown in figure. Electric field at point 'P' will be :

Three large parallel plates have unifrom surface charge densities as shown in the figure. What is the electric field at P .

A parallel plate capacitor has an electric field of 10^(5)V//m between the plates. If the charge on the capacitor plate is 1muC , the force on each capacitor plate is
