A charge $q$ is located at the centre of a cube. The electric flux through any face is
$\frac{{4\pi q}}{{6(4\pi {\varepsilon _0})}}$
$\frac{{\pi q}}{{6(4\pi {\varepsilon _0})}}$
$\frac{q}{{6(4\pi {\varepsilon _0})}}$
$\frac{{2\pi q}}{{6(4\pi {\varepsilon _0})}}$
Why do electric field lines not form closed loop ?
The electric field components in Figure are $E_{x}=\alpha x^{1 / 2}, E_{y}=E_{z}=0,$ in which $\alpha=800 \;N / C\, m ^{1 / 2} .$ Calculate
$(a)$ the flux through the cube, and
$(b)$ the charge within the cube. Assume that $a=0.1 \;m$
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
Give definition of electric flux.
