## Coulomb’s Law Practice. Una risorsa per il CLIL di Fisica in lingua inglese

red - Vengono di seguito proposti alcuni esercizi sulla legge di Coulomb, utili per le classi quinte in cui sono attivi dei percorsi CLIL di Fisica in lingua inglese.

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?
