SUMMARY
The discussion centers on calculating the magnitude of the centripetal force acting on a roller coaster at the top of a vertical loop. The minimum speed required for the roller coaster to maintain its trajectory is critical, as it determines the forces acting on it. At this point, the centripetal force is equal to the gravitational force (mg), as the normal force is zero. Therefore, the correct answer to the problem is option (a) mg.
