A stone is rotated in a vertical circle. Speed at bottommost point is `sqrt(8gR)`, where R is the radius of circle. The ratio of tension at the top and the bottom is

A stone of mass 1 kg tied to a string 4 m long and is rotated at constant speed of 40 m/s a vertical circle. The ratio of the tension at the top and the bottom, is (g=10" m"//"s"^(2))

A stone of mass 1 kg tied to a string 4 m long and is rotated at constant speed of 40 m/s a vertical circle. The ratio of the tension at the top and the bottom, is (g=10" m"//"s"^(2))

A stone of mass 1 kg is tied to a string 2m long and it's rotated at constant speed of 40 ms^(-1) in a vertical circle. The ratio of the tension at the top and the bottom is [Take g=10m s^(2) ]

A particle of mass m is rotated in a vertical circle by means of a string . The differnce in the tensions in the string at the bottom and the top of the circle would be

The velocity of a body revolving in a vertical circle of radius r at the lowest point sqrt(7gr) . The ratio of maximum tensions in the string is

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 body of mass .m. is rotating in a vertical circle of radius .r. with critical speed at the highest point. The difference in its K.E. at the top and bottom is

During motion in the vertical circle, what is the difference in tension at the top and bottom of the circle?
