the force between two charged objects is described by Coulomb's law, named after the French physicist Charles-Augustin de Coulomb. Mathematically, it can be expressed as F = k\( \frac{q_1q_2}{r^2} \), where F is the force, k is the electrostatic constant, q1 and q2 are the magnitudes of the charges, and r is the distance between the charges. This equation allows us to calculate the strength of the force between charged objects.
