Understanding Coulomb’s Law

Coulomb’s Law is a fundamental principle in physics that describes the electrostatic interaction between charged particles. Named after the French physicist Charles-Augustin de Coulomb, this law quantifies the force between two charged objects and is essential for understanding the behavior of electric fields.

The Formula for Coulomb’s Law

The mathematical formula for Coulomb’s Law is expressed as:

F = k * |q1 * q2| / r^2

Where:

Coulomb

– F represents the electrostatic force between two charges – k is the Coulomb constant (8.9875 x 10^9 N m^2/C^2) – q1 and q2 are the magnitudes of the charges – r is the distance between the charges
