Find the flux through a spherical Gaussian surface of radius (a=1m) surrounding a charge of (8.85pC).
Solution:
The value of (\epsilon_0=8.85*10^{-12})
The flux through the Gaussian surface is the charge (Q) located inside the surface. Therefore, $$ \Phi=\frac{Q}{\epsilon_0}$$ $$=8.8510^{-12}/8.8510^{-12}$$ $$=1Nm^2/C$$
