PHY 102 Gauss's Law and Electrostatic Fields Objective Question
Take CBT

Question

What is the electric field due to an infinite plane of charge with surface charge density σ?
Options
A E = σ/(2ε₀)
Correct Answer
B E = σ/ε₀
C E = σ/(4πε₀)
D E = σ/(2πε₀)
Correct Answer

Option A is the correct answer.

Detailed Explanation

For an infinite non-conducting plane, flux from both sides gives 2EA = σA/ε₀ → E = σ/(2ε₀).

Hint

Uniform field, independent of distance.
