(a) Two point charges totaling 8.50 µC exert a repulsive force of 0.100 N on one another when separated by 0.839 m. What is the charge on each?
smallest charge (µC)
largest charge (µC)
(b) What is the charge on each if the force is attractive?
smallest charge (µC)
largest charge (µC)

a. use coulombs equation
find the product q1q2
you are given q1+q2=8.5
you should get two solutions out of this, it should be a quadratic.
