A particle is tied to 20 cm long string. It performs circular motion in vertical plane. What is the angular velocity of string when the tension in the string at the top is zero

One end of a string of length 1 m is tied to a body of mass 0.5 kg. It is whirled in a vertical circle with angular velocity 4 rad s^(-1) . Find the tension in the string when the body is at the lower most point of its motion. (take, g = 10 ms^(-1) )

If a particle tied to the end of string is set in circular motion then the tension of the string is

A body of mass 40 kg is tied at one end of a string of length l. The body is oscillating in a vertical plane with angular amplitude theta_0 . What is the tension in the string when it makes and angle theta with the vertical ? If the breaking load for the string is 80 kgf, what can be the maximum angular amplitude of the body ?

A particle tied to a string describes a vertical circular motion of radius r continually. If it has a velocity sqrt(3 gr at the highest point, then the ratio of the respective tensions in the string holding it at the highest and lowest points is

A body of mass m is tied to a string of length l and whirled in a verticle cirlce. The velocity of the body at the lowest position is u. Then the tension in the string at a position when the string makes an angle theta with the vertical is
