उत्तर

The electric flux through a closed Gaussian surface depends upon net charge enclosed and permittivity of the medium.

Explanation:

According to Gauss’s law, the total electric flux through a closed Gaussian surface is given by:

Φ = `Q_"enclosed"/epsilon`

Hence, electric flux depends on the net charge enclosed and the permittivity of the medium, and not on the size or shape of the surface.
