Choose the correct answer from given options
The electric flux through a closed Gaussian surface depends upon
पर्याय
Net charge enclosed and permittivity of the medium
Net, charge enclosed, permittivity of the medium and the size of the Gaussian surface
Net charge enclosed only
Permittivity of the medium only
उत्तर
The electric flux through a closed Gaussian surface is given by:
`oint vec"E"."d" vec"s" = "q"/in`
Where, q is the net charge enclosed by the Gaussian and ∈ is the permittivity of the medium.
Hence, the correct answer is Net charge enclosed and permittivity of the medium.
