A mass is tied to a, string 1 m long and rotated in a horizontal circle at the rate of 600 rpm. If the tension inthe string is 3943.8 N, calculate the mass.

A particle of mass 14 g attached to a string of 70 cm long is rotated in horizontal circle. If the period of revolution is 2 sec, find the tension in the string.

A mass m moves in a circle on a smooth horizontal plane with velocity v_0 at radius R_0 . The mass is attached to a string which passes through a smooth hole in the plane as shown.The tension in the string is increased gradually and finally m moves in a circle of radius R_0/2 .The final value of the kinetic energy is : .

A uniform rod of mass 15 kg is held stationary with the help of a light string as shown in Fig. The tension in the string is

A mass M is hung with a light inextensible string as shown in Find the tension in the horizontal part of the string .

A particle of mass m is rotated in a vertical circle by means of a string . The differnce in the tensions in the string at the bottom and the top of the circle would be
