A point charge $ + q$ is placed at the centre of a cube of side $L$. The electric flux emerging from the cube is
$\frac{q}{{{\varepsilon _0}}}$
Zero
$\frac{{6q{L^2}}}{{{\varepsilon _0}}}$
$\frac{q}{{6{L^2}{\varepsilon _0}}}$
A long cylindrical volume contains a uniformly distributed charge of density $\rho$. The radius of cylindrical volume is $R$. A charge particle $(q)$ revolves around the cylinder in a circular path. The kinetic of the particle is
What can be said for electric charge if electric flux assocaited with closed loop is zero ?
A charge $Q\;\mu C$ is placed at the centre of a cube, the flux coming out from any surfaces will be
Linear charge density of wire is $8.85\,\mu C/m$ . Radius and height of the cylinder are $3\,m$ and $4\,m$ . Then find the flux passing through the cylinder
What is called Gaussian surface ?
