A particle of mass 21 g attached to a string of 70 cm length is whirled round in a horizontal circle. If the period of revolution is 2s, find the tension in the string.

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 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 stone of mass of 16 kg is attached to a string 144 m long and is whirled in a horizontal circle. The maximum velocity of revolution that can be given to the stone without breaking it, will be (Breaking tension is 16 N)

A stone of mass 0.5 kg is attached to a string of length 2 m and is whirled in a horizontal circle. If the string can with stand a tension of 9N, the maximum velocity with which the stone can be whirled is:
