Question

The electric flux through a closed Gaussian surface depends upon ______.

Options

  • Net charge enclosed, permittivity of the medium and the size of the Gaussian surface.

  • Net charge enclosed only.

  • Permittivity of the medium only.

Solution

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.
