$A$ region surrounding a stationary electric dipole has:

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

Two ideal electric dipoles $A$ and $B$ having dipole moments $p_{1}$ and $p_{2}$ respectively are placed on a plane with their centers at $O$ as shown in the figure. At point $C$ on the axis of dipole $A$,the resultant electric field makes an angle of $37^{\circ}$ with the axis. The ratio of the dipole moments of $A$ and $B$,$\frac{p_{1}}{p_{2}}$ is $....$ (take $\sin 37^{\circ}=\frac{3}{5}$)

The electric dipole moment of a short electric dipole is $p$. The electric potential at a point at a distance $r$ from its center and making an angle $\theta$ with the axis of the dipole is .......

What does an electric dipole experience when placed in a non-uniform electric field?

An electric dipole with dipole moment $4 \times 10^{-9} \text{ Cm}$ is aligned at $60^{\circ}$ with the direction of a uniform electric field of magnitude $5 \times 10^4 \text{ NC}^{-1}$. Calculate the magnitude of the torque acting on the dipole.
