The angle between the electric dipole moment of a dipole and the electric field strength due to it on the equatorial line is (in $^{\circ}$)

An electric dipole is placed in a non-uniform electric field,then . . . . . . .

Two short electric dipoles are placed as shown. The energy of electric interaction between these dipoles will be

An electric dipole with dipole moment $4 \times 10^{-9} \;C \,m$ is aligned at $30^{\circ}$ with the direction of a uniform electric field of magnitude $5 \times 10^{4} \;N\,C ^{-1}$. Calculate the magnitude of the torque acting on the dipole.

Torque acting on an electric dipole in a uniform electric field is maximum when the angle between $\vec{p}$ and $\vec{E}$ is . . . . . . . (in $^{\circ}$)

An electric dipole is placed in a non-uniform electric field. It may experience:
