Three masses are placed on a rotating table at distances 6 cm, 9 cm and 12 cm respectively

      

Three masses are placed on a rotating table at distances 6 cm, 9 cm and 12 cm respectively from the centre of rotation. When the frequency of rotation is varied, it is noted that each mass slides off at a different frequency of rotation of the table. Table 1 shows the frequency at which each mass slides off.

John
(i) - Mass

- Friction force

- Radius

(ii) The oil will reduce friction and since friction provides centripetal force, the frequency for sliding off is lowered.

Next: Figure 12 shows masses A, B and C placed at different points on a rotating table. The angular velocity, of the table can be varied.
Previous: Figure 11 shows a stone attached to the end of a string moving in a horizontal circle with a uniform speed of 2 ms-1. When the stone reaches point X on the circle, the string breaks
