Two surfaces $S_1$ and $S_2$ are shown in figure. Flux associated with $S_1$ is ${\phi _1}$ and $S_2$ is ${\phi _2}$. Which is correct ?

A

${\phi _1} > {\phi _2}$

B

${\phi _1} < {\phi _2}$

C

${\phi _1} = {\phi _2}$

D

can’t say anything

Solution

flux through Gaussian surface $\phi=\frac{q}{\epsilon_{0}}$

therefore flux through any surface depends only on total charge inside the surface

$\Rightarrow \phi_{1}=\phi_{2}$
