(A) According to Gauss's Law,the total electric flux $\phi$ through a closed surface is given by $\phi = \frac{q_{enc}}{\epsilon_0}$,where $q_{enc}$ is the net charge enclosed by the surface.First,calculate the net charge $q_{enc}$ inside the sphere:$q_{enc} = (+2 - 5 - 3 + 6) 	imes 10^{-6} \ C$$q_{enc} = (8 - 8) 	imes 10^{-6} \ C = 0 \ C$Since the net charge enclosed is $0$,the total electric flux $\phi$ passing through the sphere is $\phi = \frac{0}{\epsilon_0} = 0$.

If the charges inside a sphere are $+2 \times 10^{-6} \ C$,$-5 \times 10^{-6} \ C$,$-3 \times 10^{-6} \ C$,and $+6 \times 10^{-6} \ C$,what is the total electric flux passing through the sphere?
