When the charges are located in some other medium rather than vaccum then the force between the charges will be :
Where  is the absolute electric permittivity of the medium and r is the seperation between the two charges.
The force between the charges held at same distance from each other in vaccum is :
Where  is the relative electrical permittivity. It is also called as dielectric constant of the separation medium between charges, and is denoted by K.
