The law that describes the interactions between charged particles when they are not in contact is Coulomb's Law.

Here's a breakdown:

* Coulomb's Law states that the electrostatic force between two point charges is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.

* This means that:

* The stronger the charges, the stronger the force.

* The closer the charges, the stronger the force.

* The force is attractive if the charges are of opposite signs and repulsive if the charges are of the same sign.
