A stone connected with a string is rotated in a vertical circle, speed of stone at bottom most point is v, where R is the radius of circle. The difference of tension in string at the bottom and the top is :-

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 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 with a string and is rotated in a circle horizontally. When the string suddenly breaks, the stone will move

A stone of mass of 1 kg is tied to the end of a string 1 m long. It is whirled in a vertical circle. The velocity of the stone at the bottom of the circle is just sufficient to take it to the top of circle without slackening of the string. What is the tension in the string at the top of the circle? (Take, g =10 ms^(-2) )

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

A ball of mass m is fastened to a string. The ball swings in a vertical circle of radius R with the other end of the string held fixed. Neglecting the air resistance, the difference between the string's tension at the bottom of the circle and at the quarter of the cirlce is

A particle of mass m attached to an inextensible light string is moving in a vertical circle of radius r. The critical velocity at the highest point is v_( 0) to complete the vertical circle. The tension in the string when it becomes horizontal is

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

A stone of mass 1kg is tied with a string and it is whirled in a vertical circle of radius 1 m. If tension at the highest point is 14 N, then velocity at lowest point will be

A particle of mass m is being circulated on a vertical circle of radius r. If the speed of particle at the highest point be v, then
