A body of mass 1 kg is tied to a string and revolved in a horizontal circle of radius 1 m. Calculate the maximum number of revolutions per minute, so that the string does not break, Breaking tension of the string is 9.86 N.

A stone of mass m is tied to a string and is moved in a vertical circle of radius r making n revolution per minute. The total tension in the string when the stone is its lowest point is.

An object of mass M is tied to a string of length l and revolved in a horizontal circle. If length is reduced by l//2 , then period is

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 body of mass 1 kg tied to one end of string is revolved in a horizontal circle of radius 0.1 m with a speed of 3 "revolution"//sec , assuming the effect of gravity is negligible, then linear velocity, acceleration and tension in the string will be

A body of mass 2 kg is tied to the end of a string 2 m long and revolved in horizontal circle. If the breaking tension of the string is 400 N, then the maximum velocity of the body will be

A body of mass 0.1 kg tied to a string of length 5 m is revolved in a vertical circle such that the maximum tension in the string is 9N. The minimum tension in the string is A. 0N B. 3N C. 4N D. 6N

A stone of mass1/2kg iswhirled round the end of a piece of string in a horizontal circle of radius half a meter with a uniform speed of 1 m//s . The tension in the string is

A stone of mass 50 g is tied to the end of a string 2 m long and is set into rotation in a horizontal circle with a uniformspeed of 2 m//s . Then tension in the string is

A stone of mass 1kg tied to a light inextensible string of length L=10m is whirling in a circular path of radius L in vertical plane. If the ratio of the maximum tension in the string to the minimum tension in the string is 4 and if g is taken to be 10ms^(-2) , the speed of the stone at the highest point of the circle is.

An object of mass 2 kg is whirled round in a vertical circle of radius lm with a constantspeed of 4 m//s . Then the maximum tension in the string is
