Electric Charge & Coulomb's Law

When air is replaced by a dielectric medium of constant $K$ , the maximum force of attraction between two charges, separated by a distance

Show answer and solution

Answer: (a)

$F_m = \dfrac{1}{4\pi\varepsilon_0 K}\dfrac{q_1q_2}{r^2} = \dfrac{F_{air}}{K}$
So the answer is (a) the force decreases $K$ times.
