A large mass M and a small mass m hang at the two ends of a string that passes through a smooth tube as in Fig. 3.6. The mass m moves around in a circular path which lies in a horizontal plane. The length of the string from the mass m to the top of the tube is L , and T is the angle this length makes with the vertical. What should be the frequency of rotation of the mass m so that the mass M remains stationary?Solution: |
