Question

From Gauss’ law which of the following is NOT correct?
The outward flux of electric field through an enclosed surface is proportional to the electric charges enclosed
The field at a point outside a spherically symmetric charge is the same as the electric field at the same point due to a point charge at its centre.
The electric flux through a Gaussian surface is a vector product of the electric field and a unit vector perpendicular to and outward from the surface
The total electric flux through a cylinder placed in an electric field with its axis parallel to the field is zero
