A small body of mass 1/2 kg is tied to one end of a string of length 1m. With what horizontal velocity must the body be projected so that it may go round the peg to which the other end of the string is attached without slackening of the string at the highest point ?

A small body is tied to an end of an inextensible string of negligible mass and length r, the other end being clamped to a rigid support. What is the minimum velocity with which the body must be projected horizontally so that it can go completely round a vertical circle without slakening of the string at the highest point ?

A stone of mass of 1 kg is tied to the end of a string 1 m long. It is whirled in a vertical circle. The velocity of the stone at the bottom of the circle is just sufficient to take it to the top of circle without slackening of the string. What is the tension in the string at the top of the circle? (Take, g =10 ms^(-2) )

A stone of mass 250 gram , attached at the end of a string of length 1.25 m is whirled in a horizontal circle at a speed of 5 m/s . What is the tension in the string ?

A body of mass m tied at the end of a string of length l is projected with velocity sqrt(4lg), at what height will it leave the circular path

A body of mass 2 kg is tied to the end od a string 2 m long and revolved in horizontal circle .If the breaking tension of the string is 400 N, then the maximum velocity of the body will be

Stone of mass 1 kg tied to the end of a string of length 1m , is whirled in horizontal circle with a uniform angular velocity 2 rad s^(-1) . The tension of the string is (in newton)

A body of mass 100 gram is tied at the end of a string of length 1m. It is rotated in a vertical circle at a critical speed of 4 m/s at the highest point . The tension in the string at the huighest point in its path is [ take g=10 m//s^(2) ]

A stone of mass 5 kg is tied to a string of length 10 m is whirled round in a horizontal circle. What is the maximum speed with which the stone can be whirled around if the string can withstand a maximum tension of 200 N?
