Question

Choose the incorrect statement:
(a) The electric lines of force entering into a Gaussian surface provide negative flux.
(b) A charge $q$ is placed at the centre of a cube. The flux through all the faces will be the same.
(c) In a uniform electric field net flux through a closed Gaussian surface containing no net charge, is zero.
(d) When an electric field is parallel to a Gaussian surface, it provides a finite non-zero flux.

We know that electric flux is a scalar quantity and this is the scalar product of the magnitude of electric field and surface area.

Recall, the formula given by Gauss theorem, $ϕ = \vec{E} \cdot \vec{A} = E A \cos θ$ , here $θ = 90 °$ , it means, $ϕ = 0$ .
