A small metal sphere, carrying a net charge of q1 = -3.00 µC, is held in a stationary position by insulating supports. A second small metal sphere, with a net charge of q2 = -7.20 µC and mass 1.90 g, is projected toward q1. When the two spheres are 0.800 m apart, q2 is moving toward q1 with speed 22.0 m/s (Figure 1). Assume that the two spheres can be treated as point charges. You can ignore the force of gravity.
