Coulomb's Law PhET Simulation: Investigation of How Distance Between Charges Affects Electrostatic Force
For this part, we will be adjusting the DISTANCE ONLY.
Set charge 1 for -4 µC
Set charge 2 for 8 µC
Given the charge values and the distances, determine the electrostatic force between the charged particles and if they are attracted, repelled, or neither.
*If two charges are attracted, their electrostatic force is negative**
**If the two charges are repelled, their electrostatic force is positive**
Charge 1 Charge 2 Distance Apart
Trial 1 -4 pC 8 pC 2 cm
Trial 2 -4 pC 8 pC 4 cm
Trial 3 -4 pC 8 pC 6 cm
Trial 4 -4 pC 8 pC 8 cm
