Coulomb’s Law Practice

1. Two particles, each with a charge of 1 C, are separated by a distance of 1 meter. What is the force between the particles?

2. What is the force between a 3 C charge and a 2 C charge separated by a distance of 5 meters?

3. Calculate the force between a 0.006 C charge and a 0.001 C charge 4 meters apart.

4. Calculate the force between a 0.05 C charge and a 0.03 C charge 2 meters apart.

5. Two particles are each given a charge of 5 x 10-5 C. What is the force between the charged particles if the distance between them is 2 meters?

6. The force between a pair of charges is 100 newtons. The distance between the charges is 0.01 meter. If one of the charges is 2 x 10-10 C, what is the strength of
the other charge?

7. Two equal charges separated by a distance of 1 meter experience a repulsive force of 1,000 newtons. What is the strength in coulombs of each charge?

8. The force between a pair of 0.001 C charges is 200 N. What is the distance between them?

9. The force between two charges is 1000 N. One has a charge of 20µC, and the other has a charge of 5 µC. What is the distance between them?

10. The force between two charges is 2 newtons. The distance between the charges is 2 x 10-4 m. If one of the charges is 3 µC, what is the strength of the
other charge?
