Electric flux through surface $s_1$
is minimum
is maximum
equal to $s_2$ but less than $s_4$
equal for all surfaces
Flux do not depend upon shape
A cube of side $l$ is placed in a uniform field $E$, where $E = E\hat i$. The net electric flux through the cube is
A long cylindrical volume contains a uniformly distributed charge of density $\rho \;Cm ^{-3}$. The electric field inside the cylindrical volume at a distance $x =\frac{2 \varepsilon_{0}}{\rho} m$ from its axis is $…….Vm ^{-1}$
A charge of $1$ coulomb is located at the centre of a sphere of radius $10 \,cm$ and a cube of side $20 \,cm$. The ratio of outgoing flux from the sphere and cube will be
A charge $q$ is surrounded by a closed surface consisting of an inverted cone of height $h$ and base radius $R$, and a hemisphere of radius $R$ as shown in the figure. The electric flux through the conical surface is $\frac{n q}{6 \epsilon_0}$ (in SI units). The value of $n$ is. . . .
Explain the electric field lines and the magnitude of electric field.
