In the absence of electric filed, the dipole moment of ${\mathrm{CO}}_2$ is _____ .

${\mathrm{H}}_2\mathrm{O}$ has a permanent dipole moment.

When the centres of positive charges and negative charges lie at same place, their dipole moment is zero.

Calculate the electric field due to a dipole at a point on the equatorial plane.

What is the unit of electric dipole moment?

Define ‘Electric dipole’

An electric dipole of moment $\overrightarrow{P}$ is placed in a uniform electric field $\overrightarrow{E}$ . Then, the potential energy of the system is $\overrightarrow{P}·\overrightarrow{E}$.

In a system two charges $q_A=2.5\times {10}^{-7} \mathrm{C}$ and $q_B=-2.5 \times {10}^{-7} \mathrm{C}$ are situated at point $A(0, 0, -15 \mathrm{cm})$ and $B(0, 0, + 15 \mathrm{cm})$. Find the electric dipole moment of the system.

What is the net force (in SI units) on an electric dipole in a uniform electric field?
(Give only the magnitude of the solution).

For the same distance from centre of the dipole the ratio of electric fields at longitudinal and transverse position is 

An electron and a proton are $1 \mathrm{m}$ apart. The dipole moment of the system is (Take, $e=1.6\times {10}^{-19} \mathrm{C}$)

The dipole moment of $\mathrm{HCl}$ molecule is  $3.4\times {10}^{-30}$ $\mathrm{C}-\mathrm{m}$. The separation between its ions is ($e=1.6\times {10}^{-19} \mathrm{C}$)
