23.5 ●● A small metal sphere, Figure E23.5 carrying a net charge of 9₁ = -2.80 µC, is held in a stationary position by insulat- ing supports. A second small metal sphere, with a net charge of 92 = -7.80 µC and mass 1.50 g, is projected toward 91. When the two spheres are 0.800 m apart, q2, is moving toward qı with speed 22.0 m/s (Fig. E23.5). Assume that the two spheres can be treated as point charges. You can ignore the force of gravity. (a) What is the speed of 92 when the spheres are 0.400 m apart? (b) How close does 92 get to 9₁? 92 v = 22.0 m/s -0.800 m 91
