A charge Q C is placed at the center of a cube. If ₀ is the permittivity of vacuum then the flux through one face and two opposite faces of the cube is respectively

Options

  1. AQ 6 ₀ , Q 3 ₀
  2. BQ 3 ₀ , Q 2 ₀
  3. CQ 12 ₀ , Q 6 ₀
  4. DQ ₀ , Q 2 ₀

Correct answer

A. Q 6 ₀ , Q 3 ₀

Step-by-step solution

A charge Q C is placed at the center of a cube. Total flux radiated = Q ₀ from one face would be Q 6 ₀ due to the six-fold symmetry of the cube. And from two opposite faces, it would be Q 3 ₀ due to three-fold symmetry.
