Electric field intensity due to infinite sheet of charge σ is(a) Zero

1.	Electric field intensity due to infinite sheet of charge σ is(a) Zero(b) Unity(c) σ/ε(d) σ/2εThis question was addressed to me in an interview.I want to ask this question from Electric Field Intensity in section Electrostatic Fields of Electromagnetic Theory
Answer» Right answer is (d) σ/2ε For explanation I would say: E = σ/2ε.(1- cos α), where α = h/(√(h^2+a^2)) Here, h is the DISTANCE of the SHEET from point P and a is the radius of the sheet. For INFINITE sheet, α = 90. Thus E = σ/2ε.
