The torque acting on a dipole of moment $\overrightarrow{P}$ in an electric field $\overrightarrow{E}$ is:

When is the torque on an electric dipole in an electric field maximum?

In the case of the dimensions of electric field and electric dipole moment,the power of mass is respectively:

An electric dipole is placed on the $x$-axis as shown in the figure. Consider a spherical closed surface around it. Then,

Two electric dipoles of moment $P$ and $27 P$ are placed on a line with their centres $24 \,cm$ apart. Their dipole moments are in opposite directions. At which point between the dipoles, measured from the centre of the dipole of moment $P$, will the electric field be zero (in $\,cm$)?

The angle between the electric field and the dipole moment at any point on the equatorial plane of an electric dipole is . . . . . . . (in $^{\circ}$)
