A stone is tied to a weightless string and revolved in a vertical circle of radius 5 m . What should be the minimum speed of the stone at the highest point of the circle so that the string does not slack ? What should be the speed of the stone at the lowest point of vertical circle ? Take ` g = 9.8 ms^(2) ` .

A stone is fastened to one end of a string and is whirled in a verticla circle of radius R. Find the minimum speed the stone can have at the highest point of the circle.

A particle of mass m is tied to a light string of length l and rotated along a vertical circular path. What should be the minimum speed at the highest point of its path so that the string does not become slack at any position ?

A stone is tied to one end of a string and rotated in a vertical circle . What is the difference in tensions of the string at lowest and highest points of the vertical circle ?

A small stone of mass 50 g is rotated in a vertical circle of radius 40 cm. What is the minimum tension in the string at the lowest point?

A stone of mass 0.4 kg is tied to a string and rotated in a vertical circle of radius 1.2 m . Calculate the speed of the stone for which the tension in the string is zero at the highest point of the circle . What is the tension at the lowest point in this case ?

A small stone of mass 200 g is tied to one end of a string of length 80 cm . Holding the other end in hand , the stone is whirled into a vertical circle What is the minimum speed that needs to be imparted at the lowest point of the circular path , so that the stone is just able to complete the vertical circle ? what would be the tension at the lowest point of circular path ? (Take g = 10 m//s^(2)) .
