Question

In the figure a very large plane sheet of positive charge is shown. P₁ and P₂ are two points at distance ℓ and 2ℓ from the charge distribution. If σ is the surface charge density, then the magnitude of electric fields E₁ at E₂ at P₁ and P₂ respectively are:

E₁ = E₂ = σ/ε₀

E₁ = σ/ε₀, E₂ = σ/2ε₀

E₁ = 2σ/ε₀, E₂ = σ/ε₀

E₁ = E₂ = σ/2ε₀
