A ring radius R is fixed vertically to the floor. From the top of the ring and object slides down without friction. Find the distance "L" from the point of support of the ring to the point where the object hits the ground.
I think the object travels tangetially from 90 degrees from the top of the circle. This is where the normal force equals the centripetal force and the net force is the weight. Is this right? If so how do I prove this?
