SUMMARY
The discussion clarifies the use of subscripts in Coulomb's Law equations, specifically in the context of forces between electric charges. The subscripts (13 and 23) denote the specific interactions between charge pairs: F1 represents the force from charge 1 to charge 3, while F2 represents the force from charge 2 to charge 3. This notation is essential for understanding the directionality of the forces involved in electrostatic interactions. The formula used is F = k [(q1q2)/r²], where 'k' is Coulomb's constant.
