Question
For a charged non-conducting sheet (insulating sheet) with uniform surface charge density σ, what is the electric field?
Correct Answer
Option A is the correct answer.
Detailed Explanation
For a charged non-conducting sheet, field lines emanate from both sides, so total flux = 2EA = σA/ε₀, giving E = σ/(2ε₀).
Hint
Flux from both sides.
