The electric field in a region is given by $\vec E = \frac{3}{5}{E_0}\hat i + \frac{4}{5}{E_0}\hat j$ and $E_0 = 2\times10^3\, N/C$. Then, the flux of this field through a rectangular surface of area $0.2\, m^2$ parallel to the $y-z$ plane is......$\frac{{N - {m^2}}}{C}$
$240$
$320$
$0$
$560$
When the electric flux associated with closed surface becomes positive, zero or negative ?
A charge $Q\;\mu C$ is placed at the centre of a cube, the flux coming out from any surfaces will be
A charge particle is free to move in an electric field. It will travel
The figure shows some of the electric field lines corresponding to an electric field. The figure suggests
A point charge $+10\; \mu \,C$ is a distance $5 cm$ directly above the centre of a square of side $10 \;cm ,$ as shown in Figure. What is the magnitude of the electric flux through the square?
