Gauss's LawEasyQuestion 31421

Question

Gauss's law states that electric flux through a closed surface is:
  1. A
    Equal to the charge enclosed × ε₀
  2. B
    Equal to the charge enclosed / ε₀
    Correct
  3. C
    Zero always
  4. D
    Equal to the surface area

Correct answer

Equal to the charge enclosed / ε₀

Explanation

ΦE = ∮E·dA = q_enc/ε₀. The flux depends only on the charge enclosed, not on the shape of the surface.
