Noncontact forces unit test which of these factors affect electric force
1. Distance between the charged objects: The electric force between two charged objects decreases as the distance between them increases.
2. Magnitude of charge: The electric force between two charged objects increases as the magnitude of the charges on the objects increases.
3. Medium between the charged objects: The electric force may be affected by the presence of a medium (such as air or water) between the charged objects, which can alter the strength of the force.
