What is (a) electric dipole moment , (b) dielectric strength ?

What is an electric dipole ?

Define dipole moment.

The unit of electric dipole moment is:

What is the angle between electric dipole moment and the electric field strength E when the dipole is in stable equilibrium ?

The angle between the electric dipole moment and the electric field strength due to it on the axial line is

A parallel plate capacitor is to be designed with a voltage rating 1 kV, using a material of dielectric constant 3 and dielectric strength about 10^(7) Vm^(-1) . (Dielectric strength is the maximum electric field a material can tolerate without breakdown, i.e., without starting to conduct electricity through partial ionisation.) For safety, we should like the field never to exceed, say 10% of the dielectric strength. What minimum area of the plates is required to have a capacitance of 50 pF?

The torque on an electric dipole of moment p when placed in electric field E is proportional to :

Dipole moment of CO_(2) is zero.

What is the effect of dielectric medium on the electric potential of a capacitor ?

Which has maximum dipole moment ?
