A charge Q is uniformly distributed over a large plastic plate. The electric field at point P close to centre of plate is 10Vm⁻¹. If the plastic plate is replaced by copper plate of the same geometrical dimension and carrying the same charge Q, then the electric field at that point will be
Options
(a) zero
(b) 5Vm⁻¹
(c) 10Vm⁻¹
