Question

As per Gauss law, $\int \overrightarrow{E.}\overrightarrow{ds}=\frac{q_{enclosed}}{{\epsilon }_0}$
. Which of the following is true about this?

• A. This is only valid for symmetrical surface
• B. $E$ is the electric field due to the charge inside the surface
• C. Electric flux through the closed surface due to outside charge is always zero
• D. The flux also include surface parallel to it

Answer 1

The correct option is C Electric flux through the closed surface due to outside charge is always zero

Electric flux is always due to the charge inside the gaussian surface.
