Two blocks of mass m 1=10 kg and m 2 =5 kg connected to each other by a massless inextensible string of length 0.3m are placed along a diameter of a turn table. The coefficient of friction between the table and m 1 is 0.5 while there is no friction between m 2 and the table. The table is rotating with an angular velocity of 10 rad/sec about a vertical axis passing through its center. The masses are placed along the diameter of the table on either side of the center O such that m 1 is at a distance of 0.124 m from O. The masses are observed to be at rest with respect to an observer on the turn table.

A smooth semicircular wire track of radius R is fixed in a vertical plane (see Fig.6.201). One end of a massless spring of natural length (3/4) R is attached to the lowest point o of the wire track. A small ring of mass m, which can slide on the track, A small ring of mass m, which can slide on the track, is attached to the other end of the spring. The ring is held stationary of point P such that the spring makes an angle of 60 0 with the vertical. The spring constant k=(mg/R). Consider the instant when the ring is making an angle 60 degree with the vertical.
