If a point charge q is placed at the centre of a cube what is the flux linked with each face of the cube? |
$\phi=\frac{1}{\epsilon_0} q$ $\phi=\frac{3}{\epsilon_o} q$ $\phi=\frac{6}{\epsilon_o} q$ $\phi=\frac{1}{6 \in_o} q$ |
$\phi=\frac{3}{\epsilon_o} q$ |
Now as cube is a symmetrical body with a faces and the point charge is at its centre, so electric flux linked with each face will be $\phi_{F}=\frac{1}{6} \phi=\frac{q}{6 \in_{o}}$ |
