Options
`Q/(12epsilon_0) muV"m", Q/(3epsilon_0) muV"m"`
`Q/(6epsilon_0) muV"m", Q/(2epsilon_0) muV"m"`
`Q/(6epsilon_0) muV"m", Q/(3epsilon_0) muV"m"`
`Q/(12epsilon_0) muV"m", Q/(epsilon_0) muV"m"`

Solution
A charge 'Q' µC is placed at the centre of a cube. The flux through one face and two opposite faces of the cube is respectively `Q/(6epsilon_0) muV"m", Q/(2epsilon_0) muV"m"`.
Explanation:
Total flux radiated `=Q/epsilon_0`
∴ from one side `Q/(6epsilon_0)`
from two opposite sides `Q/(3epsilon_0)`
