A charge $q$ is placed at the center of one of the surface of a cube. The flux linked with the cube is :-
$\frac{q}{4 \epsilon_0}$
$\frac{q}{2 \epsilon_0}$
$\frac{q}{8 \epsilon_0}$
Zero
Linear charge density of wire is $8.85\,\mu C/m$ . Radius and height of the cylinder are $3\,m$ and $4\,m$ . Then find the flux passing through the cylinder
Give definition of electric flux.
Figure shows electric field lines due to a charge configuration, from this we conclude that
If the electric field intensity in a fair weather atmosphere is $100 \,V / m$, then the total charge on the earth's surface is ............ $C$ (radius of the earth is $6400\,km$ )
An electric field converges at the origin whose magnitude is given by the expression $E = 100\,r\,Nt/Coul$, where $r$ is the distance measured from the origin.
