Question

A cube of area A encloses a charge of 10​​​​ micro coulomb . if the cube is replaced by a sphere of same area . find the ratio of flux through sphere and cube

Answer 1

$$\begin{gathered} AccordingtotheGausslaw: \\ fluxthroughanybodyisgivenby: \\ \varphi =\frac{netchargeenclosed}{{\epsilon }_0} \\ \sin cechargeenclosedbythecubeandthesphereissamethereforefluxthoughbothbodyissame. \\ hence \\ \frac{fluxthroughcube}{fluxthroughsphere}=1:1 \end{gathered}$$
