How does the Coulomb force between two point charges depend upon the dielectric constant of the intervening medium?

Explanation

To understand how the Coulomb force between two point charges depends on the dielectric constant of the intervening medium, we can follow these steps:

### Step 1: Understand Coulomb's Law
Coulomb's Law states that the force \( F \) between two point charges \( Q_1 \) and \( Q_2 \) separated by a distance \( r \) in a vacuum is given by:
\[ F = k \frac{Q_1 Q_2}{r^2} \]
where \( k \) is the Coulomb's constant.
