Given
We know that,
Electric field due to the uniformly charged large surface is given as:
E = σ/ 2ϵo ----- (1)
From equation (1) it is clear that the electric field due to a uniformly charged surface is independent of distance from the surface.
It only depends on the surface density.
Hence in both cases, the Electric field will be the same, i.e.
E1 = E2 = σ/ 2ϵo
Hence option 3) is the correct choice.
