The title of the Project: Coulomb’s law

Purpose of the work:

Study Coulomb’s law.

Practical part

Choose “Macro Scale” to start the virtual experiment.

This is a little instruction to the virtual experiment.

Part 1. Charge dependence of the electrostatic force

Virtual experiment.

Step 1. Increase the charge of the first body. How does the force change?

Step 2. Increase the charge of the second body. How does the force change?

Step 3. Decrease the charge of the first body. How does the force change?

Step 4. Decrease the charge of the second body. How does the force change?

Step 5. Make a conclusion.

Part 2. Distance dependence of the electrostatic force

Virtual experiment.

Step 1. Increase the distance between the bodies. How does the force change?

Step 2. Decrease the distance between the bodies. How does the force change?

Step 3. Make a conclusion.

Conclusion

According to Coulomb’s law the electrostatic force is directly proportional to the product of the charges and inversely proportional to the square of the distance.
