An electric dipole is put in north-south direction in a sphere filled with water. Which statement is correct
Electric flux is coming towards sphere
Electric flux is coming out of sphere
Electric flux entering into sphere and leaving the sphere are same
Water does not permit electric flux to enter into sphere
How does the no. of electric field lines passing through unit area depend on distance ?
What will be the total flux through the faces of the cube as in figure with side of length $'a'$ if a charge $'q'$ is placed at ?
$(a)$ $C$ $:$ centre of a face of the cube.
$(b)$ $D$ $:$ midpoint of $B$ and $C$.
The spatial distribution of the electric field due to two charges $(A,\,B)$ is shown in figure. Which one of the following statements is correct ?
The figure shows some of the electric field lines corresponding to an electric field. The figure suggests
A point charge $q$ is placed at a distance $a/2$ directly above the centre of a square of side $a$. The electric flux through the square is
