How does the electric field lines depend on area ?
A hollow cylinder has a charge $q$ coulomb within it. If $\phi$ is the electric flux in units of $volt-meter$ associated with the curved surface $B,$ the flux linked with the plane surface $A$ in units of $V-m$ will be
For a given surface the Gauss's law is stated as $\oint {E \cdot ds} = 0$. From this we can conclude that
A charge $Q\;\mu C$ is placed at the centre of a cube, the flux coming out from any surfaces will be
Write $SI$ unit of electric flux.
Give definition of electric flux.
