Question

Shown below is a distribution of charges. The flux of electric field due to these charges through the surface S is :

• A. $\frac{3q}{{\epsilon }_0}$
• B. $\frac{2q}{{\epsilon }_0}$
• C. $\frac{q}{{\epsilon }_0}$
• D. Zero

Answer 1

The correct option is D Zero

The flux through a closed area S is given by $\varphi =\frac{q_{net}}{{ϵ}_o}$

Where $q_{net}$ is the algebraic sum of all the charges inside of the area S.

Hence, here $q_{net}=q+(-q)=0$

Hence,$\varphi =0$

Answer-(D)
