A 100 g mass is going in a vertical circle of rdius 1 m.What is the minimum speed that mass will reach at the top of the circle ?what is is speed at the bottom of circle?

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) ) .

A small stone, of mass 0.2 kg, tied to a massless, inextensible string, is rotated in vertical circle of radius 2 m. if the particle is just able to complete the vertical circle, what is its speed at the highest point of its circular path? How would this speed get effected if the mass of the stone is increased by 50%? (Take g = 10 ms^(-2) )

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

A body weighing 0.4 kg is whirled in a vertical circle making 2 revolutions per second .If the radius of the circole is 1.2m,fing the tension in the sting when the body is (a) at thge top of the circle .(b) at the bottom of the circle.

What must be the minimum speed of the body at the lowest point ,so that it may complete the vertical circle?

A simple pendulum of length l and with a bob of mass m is moving along a ricular are of anle theta in a vertical plane.A sphere of mass m is placed at the end of the circle.What momentum will be given to the sphere by the moving bob?

A particle of mass 150 g is attached to one end of a massless inextensible string It is made to describe a vertical circle of radius 1 m When the string is making an angle of 48.2^(@) with the vertical , its instantaneous speed is 2 m//s What is the tension in the string in this position ? Would this particle be able to complte its circular path?(Take g=10 m s^(-2) ).

A bob of mass m suspended by a light string of length L is whirled into a vertical circle as shown in the figure. What will be the trajectory of the particle if the string is cut at Point B?

A bob of mass m suspended by a light string of length L is whirled into a vertical circle as shown in the figure. What will be the trajectory of the particle if the string is cut at Point X?
