let the point charges be q1 and q2, and the distance between them be d.
Now, let the permeability of the medium be €r
Thus, from coulomb law, the expression is,

F = q1*q2/(4π€r*d^2)

F=\dfrac{1}{4\pi \epsilon_o\epsilon_r}\dfrac{q_1q_2}{r^2}

Explanation:

The electrostatic force exists between two charged particles. It is given by the formula as follows :

F=\dfrac{kq_1q_2}{r^2}

Where

r is the distance between charges

k is the electric constant

k=\dfrac{1}{4\pi \epsilon_o}

\epsilon_o is the permitivity of free space.

For any medium,

k=\dfrac{1}{4\pi \epsilon_o\epsilon_r}

So,

F=\dfrac{1}{4\pi \epsilon_o\epsilon_r}\dfrac{q_1q_2}{r^2}

Hence, this is the required solution.
