A charge $Q\;\mu C$ is placed at the centre of a cube, the flux coming out from any surfaces will be
$\frac{Q}{8 \varepsilon_{0}}$
$\frac{Q}{24\varepsilon_{0}}$
$\frac{Q}{6 \varepsilon_{0}} \times 10^{-3}$
$\frac{Q}{6 \varepsilon_{0}} \times 10^{-6}$
$q_1, q_2, q_3$ 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
What is called Gaussian surface ?
The figure shows some of the electric field lines corresponding to an electric field. The figure suggests
Eight dipoles of charges of magnitude $e$ are placed inside a cube. The total electric flux coming out of the cube will be
Four closed surfaces and corresponding charge distributions are shown below
Let the respective electric fluxes through the surfaces be ${\phi _1},{\phi _2},{\phi _3}$ and ${\phi _4}$ . Then
