$(8$ pts$)$ An object is sliding $($not rolling$)$ along a frictionless ramp. $($In other words, ignore all rotational kinetic energy associated with the rolling of the object.$)$ It then goes around three loops of equal radii. In the highest point of which loop is the normal force that the track exerts on the object largest in magnitude? Assume that the object makes it fully around each loop and never loses contact with the track. A$.$ Loop $3$ B$.$ Loop $1$ C$.$ Loop $2$ D$.$ The normal force is the same for all three loops. E$.$ The track exerts no normal force at the top of any loop.
