Follow the instructions and safety procedures. The attraction is then computed using Hooke’s law (Hooke 1678) and the repulsion using Coulomb’s law (Coulomb 1785). In this expression is proportionality constant. This makes sense because opposite charges attract and the force on the test charge will tend to push it toward the original positive charge creating the field. PHYS113 Lab1: Coulomb’s Law ABSTRACT Performing this experimentation will allow one to investigate the relationship quantitative relationship between the electrostatic force and the distance between charged objects.
