Vedclass · Answer

(A) According to Gauss's Law,the total electric flux $\Phi_E$ through a closed surface is given by $\Phi_E = \frac{q_{net}}{\epsilon_0}$,where $q_{net}$ is the net charge enclosed by the surface.If the electric flux $\Phi_E$ is zero,then $\frac{q_{net}}{\epsilon_0} = 0$,which implies that $q_{net} = 0$.This means that either there is no charge inside the surface,or the sum of positive and negative charges inside the surface is zero.It does not necessarily mean that there is no electric field at the surface,as charges outside the surface can contribute to the electric field but not to the net flux through the closed surface.Therefore,the net charge enclosed must be zero.

What can be said about the electric charge if the electric flux associated with a closed loop (surface) is zero?
