What is graph A?
400
Charges A and B are placed a distance of 1.5m from one another. The charge of particle A is 0.003C whereas the charge of particle B is 0.006C. Charge B experiences an electrostatic force of FB from charge A. Similarly, charge A experiences an electrostatic force of FA from charge B. This is the ratio between FA and FB.
