What are TRUE about Gauss's Law?
I posted the same question on here, but they gave wrong answers, please don't copy them.

The charge qenc must be all the charge lying within the Gaussian surface. _ If the net flux through a Gaussian surface is zero it is certain there are no charges enclosed within the Gaussian surface. The electric field E in the integral is due only to the charge qenc Gauss' Law calculates the electric field only at the location of the Gaussian surface. The charge qenc must be all the charge lying on the Gaussian surface. Gauss's law holds only for symmetric charge distributions. A Gaussian surface must be a closed surface (must cover a volume) O A Gaussian surface is a virtual surface used only for calculations. A Gaussian surface must be a conductor. O The area vectors on the Gaussian surface must all be in the same direction as the electric field on the surface. The charge qenc must be all the charge in the problem.

Explanation / Answer

These are the truths about the Gauss's Law

The charge enclosed qenc must be all the charge lying within the Gaussian Surface.

If the net flux through a Gaussian surface is zero, it may still have some charges inside it but the net charge inside it will be zer. That means there will be equal number of positive and negative charges inside.

The electric field E in the integral is only due to the charge qenclosed.

Gauss Law calculates the electric field E only at the location of the Gaussian surface.

The qenc must be all the charge lying inside the gaussian surface and not on the gaussian surface.

Gauss law also holds for unsymmetrical charge distribution.

Gaussian surface must be enclosed.

Gaussian surface is virtual and is used only for calculations.

No, gaussian surface must not be a conductor.

The area vector must have a component in the direction of the electric field. or else the net flux will be zero.
