The $S.I.$ unit of electric flux is
Weber
Newton per coulomb
Volt $×$ metre
Joule per coulomb
$\mathrm{C}_1$ and $\mathrm{C}_2$ are two hollow concentric cubes enclosing charges $2 Q$ and $3 Q$ respectively as shown in figure. The ratio of electric flux passing through $\mathrm{C}_1$ and $\mathrm{C}_2$ is :
Write $SI$ unit of electric flux.
Why do electric field lines not form closed loop ?
Figure shows electric field lines due to a charge configuration, from this we conclude that
$q_1, q_2, q_3$ and $q_4$ are point charges located at point as shown in the figure and $S$ is a spherical Gaussian surface of radius $R$. Which of the following is true according to the Gauss's law
