## Coulomb's Law
Coulomb's law gives the magnitude of the electrostatic force between two point charges.
### Formula
**F = k * |q1 * q2| / r²**
where k = 8.9875 x 10^9 N·m²/C². Like charges repel, unlike charges attract.

Lösungsbeispiel
Two charges (1 μC and 2 μC) separated by 5 cm.
- F = k * |q1 * q2| / r²
- F = 8.9875e9 * |1e-6 * 2e-6| / 0.05²
- F = 8.9875e9 * 2e-12 / 0.0025
- F = 0.01798 / 0.0025 = 7.19 N
