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 a Gaussian surface, it provides a finite non-zero flux.
Choose the most appropriate answer from the options given below :
