Two charged spheres on a frictionless horizontal surface are attached to opposite ends of a 500 N/m spring & are in static equilibrium. The 21 kg red sphere has more charge than the 17 kg green sphere. The total charge magnitude on the spheres is 16 C & they have opposite polarity. As a result the spring is compressed 0.02 m & the centers of the spheres are 0.09 m apart. Determine the charge magnitude on each sphere. Submit Answer Qred (bigger charge) - Qgreen (smaller charge) - =
