For charges q1 and q2, if force between them for some separation in air is F, then force between them - Physics - Electrostatic Potential And Capacitance

Question

For charges q1 and q2, if force between them for some separation in
air is F, then force between them in a medium of permitivity will
be?

Dear Student ,
When a new medium is introduced between the charges q1
and q2 , then the electrostatic force will be ,
F=14πε0εrq1q2r2Here , permittivity of the medium,ε=ε0εrεr=εε0
