Expert Solution
Step 1

If there are two charges place at some distance from each other, any of the charges can be treated as the test charge. The magnitude of the electrostatic force can be calculated using Coulomb’s law. And from the 3rd law of Newton, the charges exert equal and oppositely directed force on each other.
