The drawing shows a steel ball rolling along a flat surface at constant velocity from point A to point B. A magnet exerts an attractive force on the ball only for the short time that passes as the ball rolls past point B. Which one of the following trajectories does the ball follow beyond point B and why?




The ball is slightly deflected toward the magnet, and it follows path 2.


The magnet has no affect on the steel ball, so it follows path 3.


The ball is slightly deflected away from the magnet, and it follows path 4.


The ball follows the nearly circular path, 5, because a repulsive force continues to act on it.


The ball follows the nearly circular path, 1, because an attractive force continues to act on it.
