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

Options

A. `5Vm^(-1)`
B. zero
C. `10Vm^(-1)`
D. `20 Vm^(-1)`

Answer

C

Explanation

Electric field will remain same.
