Electric Flux

The SI unit of electrical flux is:

If $\underset{S}{\oint } \overrightarrow{E}·d\overrightarrow{S}=0$ over a surface, then:

A uniform electric field is applied parallel to the base of a regular circular cone pyramid as shown. The flux through the curved surface is

Coordinates of a square are given as $(1, 1, 0) \mathrm{m},$ $(1,1,0) \mathrm{m}$ $(-1,-1, 0) \mathrm{m}$, $(1,-1,0) \mathrm{m}$. If electric field is $10 \mathrm{V} {\mathrm{m}}^{-1}$ along z-axis, electric flux through square is

The black shapes in the figure below are closed surfaces. The electric field lines are in red. For which case, the net flux through the surfaces is non-zero?

A circular plate sheet of radius $10 \mathrm{cm}$ is placed in a uniform electric field of $2\sqrt{3}\times {10}^5 \mathrm{N} {\mathrm{C}}^{-1},$ making an angle of $60°$ with the field. Then find the electric flux through the sheet.

The net flux passing through the surface of an imaginary cube of edge length $\mathrm{a}$ placed in space having a uniform volume charge density, is $\mathrm{\varphi }$. The net flux passing through the surface of an imaginary sphere of radius $\mathrm{a}$ in the same space is

A positive point charge $Q$is placed (on the axis of the disc) at a distance of $4R$above the center of a disc of radius $R$as shown in situation $I.$The magnitude of electric flux through the disc is $\varphi .$Now, a hemispherical shell of a radius $R$is placed over the disc such that it forms a closed surface as shown in situation $\mathrm{II}.$The flux through the curved surface in the situation $\mathrm{II}$ taking direction of area vector along outward normal as positive is

In a region of space having a spherically symmetric distribution of charge, the electric flux enclosed by a concentric spherical Gaussian surface varies with a radius $r$ as 
$\mathrm{\varphi }=\left\{\begin{array}{ll}\frac{{\mathrm{\varphi }}_0{r}^2}{R^3},& r\le R\\ {\mathrm{\varphi }}_0,& r>R\end{array}\right.$ where $R$ and ${\mathrm{\varphi }}_0$ are the constants.

A square in a horizontal orientation is situated in a uniform horizontal electric field such that a line drawn in the plane of square makes angle of ${30}^0$ with electric field. If side of square is $a$ then flux through the square will be 

$400$ lines of force (M.K.S. unit) are entering (M.K.S.units) inwards while $200$ lines of force (M.K.S. unit) going outwards from the surface then the total value of charge confined to the surface will be

How much flux crosses the square plate if a point charge $\mathrm{Q}$ is placed at the corner of the plate as shown in the figure?

The net flux passing through the surface of an imaginary cube of edge length $\mathrm{a}$ placed in space having a uniform volume charge density, is $\mathrm{\varphi }$. The net flux passing through the surface of an imaginary sphere of radius $\mathrm{a}$ in the same space is

Find the maximum flux through the sphere if a ring of radius $R$ having a linear charge density $\mathrm{\lambda }$ moves towards a solid imaginary sphere of radius $\raisebox{1ex}{$R$}\!\left/ \!\raisebox{-1ex}{$2$}\right.$, such that the centre of ring passes through the centre of sphere. The axis of the ring is perpendicular to the line joining the centres of the ring and the sphere.
