A charge Q is uniformly distributed over a large plastic (non conducting)sheet The electric field at a point close to the surface is 20V/m . If the plate is replaced by a copper plate of the same geometrical dimensions and carrying the same charge Q,then what is the electric field at that point?

Answer:
5 V m-1 is the correct answer as the charge Q is uniformly distributed over a large plastic sheet.
Then electric field at a point close to the centre of the plate near the surface is 20 V/M.
Plate is replaced by a copper plate of the same geometrical dimensions and carrying the same charge Q so that the electric field at that point is 5 V m-1.
