When a particle is moving in vertical circle

For a particle moving in vertical circle,the:

A particle is moving in a vertical circle. Its

Find out F_min so that block will move

A small particle of mass m attached with a light inextensible thread of length L is moving in a vertical circle. In the given case particle is moving in complete vertical circle and ratio of its maximum to minimum velocity is 2:1 . Velocity of the particle when it is moving vertically downward is

A small particle of mass m attached with a light inextensible thread of length L is moving in a vertical circle. In the given case particle is moving in complete vertical circle and ratio of its maximum to minimum velocity is 2:1 . Kinetic energy of the particle at the lower most position is

A cabin is moving upwards with a constant acceleration g. A boy standing in the cabin wants to whirl a particle of mass m in a vertical circle of radius l . (Mass is attached to an ideal string.) Calculate minimum velocity which should be provided at lowermost point (w.r.t cabin) so that particle can just complete the circle.
