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 2 kg is tied to one end of a string of length 0.5 m. It is whirled in a vertical circle. If the velocity of stone at the top is circle is 5 ms^(-1) , the tension in the string at the bottom of circle is

A stone of mass 2.0 kg is tied to the end of a string of 2m length. It is whirled in a horizontal circle. If the breaking tension of the string is 400 N, calculate the maximum velocity of the stone.
