Study Notes
Coulomb's Law
- Two charges separated by distance 'r' exert a force 'F' on each other.
- If 'r' is doubled, the force 'F' becomes 1/4 of the original force.
- If 'q₁' is doubled, the force 'F' becomes 2 times the original force.
- If both 'q₁' and 'q₂' are doubled, and 'r' is halved, the force 'F' becomes 16 times the original force.
