Unformatted text preview: apart]. e) We want ball C to provide a force to counter ball B’s. Since the force acts to the left, we want the force by C on A to be to the right. A and C have the same sign of charge and will repel. Therefore, you need to place Ball C to the left of A. f) Ball C should be a distance d to the left of Ball A. g) Ball C should be a distance d / 2 to the left of Ball A. h) Ball C should be a distance 3 d to the right of Ball A. 2. a) Both balls will experience the same magnitude of force [Newton’s third law still applies!] b) Ball 1 will be moving faster. It experienced the same force as ball 2, but its lower mass means that the acceleration it felt was greater, and thus achieved a greater velocity. c) F 1 = kQ 1 Q 2 / r 2 = 2.7 N to the right. F 2 = 2.7 N to the left. d) a 1 = F 1 / m 1 = 270 m/s 2 to the right. a 2 = F 2 / m 2 = 67.5 m/s 2 to the left....
