A stone attached to a string is rotated in a vertical circle such that when it is at the top of the circle its speed is `V` and there is neither tension nor slacking in the string. The speed of stone when its angular displacement is `120^@` from the lowest point is

A stone tied to a string is rotated in a circle. If the string is cut, the stone flies away from the circle because

A stone tied with a string, is rotated in a vertical circle. The minimum speed with which the string has to be rotated

A stone is attached to one end of a string and rotated in a vertical circle . If the string breaks at the position of maximum tension , then it will break at

A stone tied to a string is rotated a vertical circle. The minimum speed of the stone during a complete vertical circular motion.

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 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 2 kg stone at the end of a string 1 m long is whirled in a vertical circle at a constant speed. The speed of the stone is 4 m//sec . The tension in the string will be 52 N , when the stone is

A 2kg stone at the end of a string 1 m long is whirled in a vertical circle . At a certain positon , the speed of the stone is 4m /s . The tension in the string will be 52 N, when the stone is [ g= 10 m//s^(2)]
