Comprehension 1 One twirls a circular ring of mass M and radius R near the tip of one s finger as shown in the process the finger never loses contact with the inner rim of the ring The finger traces out the surface of a cone shown by the dotted line The radius of the path traced out by the point where the ring and the finger is in contact is r The finger rotates with an angular velocity The rotating ring rolls without slipping on the outside of a smaller circle described by the point where the ring and the finger is in contact Figure 2 The coefficient of friction between the ring and the finger is and the acceleration due to gravity is g H Figure 1 R O Figure 2
