A small metal sphere, carrying a net charge q_1 = -2 mu C , is held in a stationary position by insulating supports. A second small metal sphere, with a net charge of q_2 = -8 mu C and mass 1.50 g , is projected toward q_1 . When the two spheres are 0.800 m apart, q_2 is moving toward q_1 with speed 20 ms^-1 as shown in (Fig. 3.151). Assume that the two spheres can be treated as point charges. You can ignore the force of gravity. . The speed of q_2 when the spheres are 0.400 m apart is.
