Dipole moment (μ)

The product of the magnitude of the charge (q) and distance between two charges (d) is called as dipole moment.

DIPOLE MOMENT (μ)

The product of the magnitude of the charge (q) and distance between two charges (d) is called as dipole moment.

i.e., Dipole moment μ = qd

Its unit is coulomb - metre (Cm).

Permittivity (ε)

The permittivity denotes the dielectric property of a medium. It indicates easily polarisable nature of the material. Its unit is farad metre-1.

Example:

Permittivity of vacuum or free space,

ε0 = 8.854 × 10-12 Fm-1
