Question

A charge Q is uniformly distributed over a large square plate of copper. The electric field at a point very close to the centre of the plate is 10 Vm -1. If the copper plate is replaced by a plastic plate of the same geometrical dimensions and carrying the same charge Q uniformly distributed, then the electric field at the point P will be (A) 5 Vm -1 (B) zero (C) 10 Vm -1 (D) 20 Vm -1

Electric field will remain same as charge density σ remain same ( E = σ / ε0 ).

5 $V m^{- 1}$

zero

10 $V m^{- 1}$

20 $V m^{- 1}$

Electric field will remain same as charge density $σ$ remain same $(E = σ / ε_{0})$ .

5 Vm−1

zero

10 Vm−1

20 Vm−1

Electric field will remain same as charge density σ remain same (E=σ/ε0​).

5 $V m^{- 1}$

10 $V m^{- 1}$

20 $V m^{- 1}$

Electric field will remain same as charge density $σ$ remain same $(E = σ / ε_{0})$ .
