Two charged spheres on a frictionless horizontal surface are attached to opposite ends of a 3,750 N/m spring & are in static equilibrium. The 45 kg red sphere has more charge than the 13 kg green sphere. The total charge magnitude on the spheres is 165 C & they have the same polarity. As a result the spring is stretched 0.15 m & the centers of the spheres are 0.33 m apart. Determine the charge magnitude on each sphere. Qred (bigger charge) = Qgreen (smaller charge) - =
