Coulomb’s law formula

Coulomb’s law formula describes the electrostatic force between two point charges. It is given by the following equation:

\[ F = k \frac{q1 * q2}{r^2} \]

Where:

• $F$ is the electrostatic force between the two point charges.
• $k $ is Coulomb’s constant, approximately equal to $ 8.988 * 10^9 \, N \cdot m^2/C^2 $.
• $q1 $ and $q2 $ are the magnitudes of the two-point charges.
• $r $ is the distance between the centers of the two charges.

Coulomb’s law states that the force is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them. The force is attractive for opposite charges (one positive and one negative) and repulsive for like charges (both positive or both negative).

This law is a fundamental concept in electrostatics and plays a crucial role in understanding the behavior of electric charges.
