⚛️ Core Principles
Coulomb's Law defines the interaction between electric charges, stating that like charges repel while opposite charges attract. The mathematical representation is given by the formula:
F = k * (q1 * q2) / r²
Here, F is the force, k is Coulomb's constant, q1 and q2 are the magnitudes of the charges, and r is the distance between them.
