Coulomb's Law PhET Simulation: Investigation of How Magnitude (size) of Charge Affects Electrostatic Force Part 1

Question

For this part, we will be adjusting the size of CHARGE 1 ONLY.
Set the distance between the two charges for 4 cm
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 -2 pC 8 pC 4 cm
Trial 2 -4 pC 8 pC 4 cm
Trial 3 -6 pC 8 pC 4 cm
Trial 4 -8 pC 8 pC 4 cm
