The electric lines of force entering into a Gaussian surface provide negative flux

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 electric field is parallel to the Gaussian surface, it provides a finite non-zero flux.

$When electric field is parallel to surface, it makes 90 ° angle with area vector so flux = 0$

$As ϕ = \vec{E} \cdot \vec{A} = E A \cos 90 ° = 0$
