Experimental Simulator PhET Interactive Simulations: Coulomb's Law PhET Interactive Simulations: Charges and Fields Procedure Part 1: Calculation of the Coulomb constant Getting started: Go to phet.colorado.edu. On the home scree, go and select "Physics." You should then see a list of simulations. C Law" and download the simulation. Take some time to familiarize features before beginning the experiment. 1. Fix the values of the charges q, and q, . Record the values O 2. Change the distance between the two charges. starting at a by 1 cm at each step (9 cm, 8 cm, etc.). At each step, record
