19. According to Coulomb's Law, when the distance between two particles increases, the electrostatic force **c) decreases**. (Coulomb's Law states that the force between two charged particles is inversely proportional to the square of the distance between them.)
20. The Coulomb is the SI unit for: **b) Charge**.
21. Increasing the number of coils in an electromagnet will cause the strength of the magnetic field to decrease. **False**. (Increasing the number of coils generally increases the strength of the magnetic field.)
