Question:

Gauss theorem states that $\int\limits_s\vec E.\vec{ds}=0$. It means that

Options:

E is zero on the surface.

E is perpendicular to the surface.

the total flux through the closed surface is zero.

the flux is only going out of the surface.

Correct Answer:

the total flux through the closed surface is zero.

Explanation:

The correct answer is Option (3) → the total flux through the closed surface is zero.

$\int\limits_sE.dA=0$ is a consequence of the total that there are no net electric charges enclosed by the surface, is zero.

Therefore, the amount of flux entering the surface is equal to the amount of flux leaving the surface.
