SUMMARY

Coulomb's Law quantitatively describes the repulsion between two electric charges, defined by the equation F = k * |q1 * q2| / r², where F is the force, k is the Coulomb's constant, q1 and q2 are the magnitudes of the charges, and r is the distance between them. The electric coupling constant e plays a crucial role in determining the strength of the interaction. This law is foundational in electrostatics and is essential for understanding electric forces in various physical systems.
