An electric dipole placed in a uniform electric field experiences maximum torque when the dipole is placed:

Two identical electric point dipoles have dipole moments $\overrightarrow{p}_{1} = p\hat{i}$ and $\overrightarrow{p}_{2} = -p\hat{i}$ and are held on the $x$-axis at a distance $'a'$ from each other. When released,they move along the $x$-axis with the direction of their dipole moments remaining unchanged. If the mass of each dipole is $'m'$,their speed when they are infinitely far apart is

An electric dipole is situated in an electric field of uniform intensity $E$ whose dipole moment is $p$ and moment of inertia is $I$. If the dipole is displaced slightly from the equilibrium position,then the angular frequency of its oscillations is

Two short dipoles $A$ and $B$,$A$ having charges $\pm 2 \mu C$ and length $1 \text{ cm}$,and $B$ having charges $\pm 4 \mu C$ and length $1 \text{ cm}$,are placed with their centres $80 \text{ cm}$ apart as shown in the figure. The electric field at a point $P$,equidistant from the centres of both dipoles,is . . . . . . $\text{N/C}$.

Two opposite and equal charges $4 \times 10^{-8} \, C$ are placed $2 \times 10^{-2} \, cm$ apart,forming a dipole. If this dipole is placed in an external electric field of $4 \times 10^8 \, N/C$,what are the values of the maximum torque and the work done in rotating it through $180^\circ$?

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