Answer:
Step 1: Electric field due to a uniformly charged plate
Electric field at a point P close to the centre of the plate:
E=
2ε
0
σ
Where σ=
A
Q
is the surface charge density
Step 2: Electric field due to copper plate
Both Copper plate and Plastic plate have the same charge and same dimensions.
Therefore, surface charge density (σ) would remain same in both cases.
Hence Electric field at point P will be same due to both the sheets.
∴E=10Vm
−1
