8B Worksheet Answers 1. Charge and Coulomb’s Law 1. a) Both balls will experience the same magnitude of force [Newton’s third law still applies!] b) The balls are identical, and therefore have the same mass. By F = ma , since they experience the same force, they experience the same acceleration. c) Ball A initially feels a force to the left, and will accelerate to the left. As ball A moves away from ball B, the force that it feels will decrease , since the distance separating the charge increases . The acceleration will therefore always be to the left and have a magnitude which will decrease down to zero when the balls are infinitely far apart. d) Ball A starts with zero velocity, but the non-zero acceleration gives it a velocity to the left. As time goes on, the velocity increases, but at a slower and slower rate [the acceleration is decreasing]. As the acceleration drops to zero, the ball will reach a maximum velocity [after an infinite amount of time, when the balls are ‘infinitely’ far 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
