Electric field due to an INFINITE SHEET of charge with surface charge density σ:
Aσ/ε₀
Bσ/(2ε₀)
Ckσ/r
Dσε₀
Answer & Solution
Correct answer: B. σ/(2ε₀)
E = σ/(2ε₀) on each side of the sheet. Field is perpendicular to the sheet and uniform (independent of distance). For a conductor's surface, factor is σ/ε₀ (no 2).
