Asmall metal sphere, carrying a net charge of q_1 = -2.80 mu c, is healed in a stationary position by insulating supports. a second small metal sphere, with a net charge of q_2 = -4.00 mu c and mass 1.30 g, is projected toward q_1. when the two spheres are 0.800 m apart, q_2 is moving toward zz with speed 22.0 m/s (see figure below). assume that the two spheres can be treated as point charges. you can ignore the force of gravity. what is the speed of q_2 when the spheres are 0.400 m apart how close does get q_2
