An electric dipole when placed in a uniform electric field $E$ will have minimum potential energy,if the positive direction of dipole moment makes the following angle with $E$.

Two electric dipoles of moments $p$ and $27 p$ are placed in opposite directions on a line at a distance of $24 \,cm$. The electric field will be zero at a point between the dipoles whose distance from the dipole of moment $p$ is

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

When does the torque acting on an electric dipole in a uniform electric field become zero?

If $\vec{E}_{ax}$ and $\vec{E}_{eq}$ represent the electric field at a point on the axial and equatorial lines of a dipole respectively,at a distance $r$ from the center of the dipole,where $r >> a$,which of the following relations is correct?

An electric dipole of dipole moment $p$ is aligned parallel to a uniform electric field $E$. The energy required to rotate the dipole by $90^{\circ}$ is $\left[\begin{array}{ll}\sin 0^{\circ}=0, & \sin 90^{\circ}=1 \\ \cos 0^{\circ}=1, & \cos 90^{\circ}=0\end{array}\right]$
