## Study Notes

### Coulomb's Law

• Coulomb's law calculates the electrostatic force between two point charges.
• According to Coulomb's law, the electrostatic force between two point charges is inversely proportional to the square of the distance between them.
• Coulomb discovered that the force between bodies with like electrical charges (i.e., both positive or both negative) is repulsive, meaning they push each other away.
• The equation for Coulomb's law is: F = k * (q1 * q2) / r^2, where F is the electrostatic force, k is Coulomb's constant, q1 and q2 are the magnitudes of the two point charges, and r is the distance between them.
• Coulomb showed that the force between oppositely charged bodies (i.e., one positive and one negative) is attractive, meaning they pull each other towards each other.
