PHY 102 Electrostatics: Electric Charge and Coulomb's Law Objective Question
Take CBT

Question

According to Gauss's Law, the net electric flux through any closed surface is equal to what?
Options
A The external electric field times the volume.
B The net charge enclosed divided by ε₀.
Correct Answer
C Zero, because all field lines that enter must leave.
D The surface area times the permittivity of free space.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Gauss's Law states that the total flux through a closed surface (Gaussian surface) is determined solely by the net charge located inside that surface.

Hint

Flux is proportional to 'Q enclosed'.
