depends on the thickness of the dielectric. If the charges are placed in a dielectric medium the force will be reduced to F/ k. Where F is the force in vacuum and k is the dielectric constant.

Force between two chargesq1 and q2 is given by

$F = {1 \over 4\pi\varepsilon_0}\frac{q_1q_2}{r^2}$ , ...(1)

When dielectric of strength K is introduced then the force is modified as

F' = F/K (where F is given by equation 1)

F IS INVERSLY RELATED TO K
