A charge 'q' is placed at the centre of a cube of side 'l'.What is the electric flux passing through two opposite faces of the cube?

Expert Answer:

Since, the cube encloses the charge ‘q’ the net flux through the cube (through 6 faces) is q/?0 Two faces of the cube comprises 1/3 of the total surface of the cube. Therefore, the flux through two faces is, q/3?0.
