Problem

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 \text{ 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) zero (b)

25 \text{ V/m}

(c)

50 \text{ V/m}

(d)

100 \text{ V/m}
