When the charges are situated in medium other than (vacuum / air) the force of interaction between them is given by
Fm = 1/ 4π epsilon m *q1 q2/r..........equation(1)
where epsilon m is the absolute electrical permittivity or intervening medium.
F° is the force between same charges held at same distance in vacuum medium.
F° = 1/4π epsilon° * q1 q2/ r²....... equation (2)
Dividing eq. 2 by 1
F°/Fm = epsilon m / epsilon° = epsilon r or K.
epsilon r is the relative electrical permittivity.
• K is the dielectric constant.
