A charged sphere in static equilibrium is resting on a horizontal surface. Directly above it is another charged sphere (also in static equilibrium) that is hanging from a string. The 50 kg red sphere has more charge than the 40 kg green sphere. The total charge magnitude on the spheres is 45 pc & they have opposite polarity. As a result the normal force on the red sphere is 470 N & the centers of the spheres are 0.44 m apart. Determine the charge magnitude on each sphere.
