Coulomb’s Law describes the force between two charged objects. In the formula, the ‘q’s represent the magnitudes of the electric charges of these objects. Specifically, if we denote the charges as q1 and q2, they quantify how much positive or negative charge each object has.
The law explains that the electric force between these charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them. This means that the greater the charge (the larger the values of q1 and q2), the stronger the force exerted between the two objects.
In summary, the ‘q’s in Coulomb’s Law serve as essential variables, representing the strength of the electric charges that interact according to this fundamental principle of electrostatics.
