A small coin is kept at the rim of a horizontal circular disc which is set into rotation about verticle axis passing through its centre. If radius of the disc is `5 cm and mu_(s)=0.25`, then the angular speed at which the coin will just slip off at

A small coin is kept at the rim of a horizontal circular disc which is set into rotation about vertical axis passing through its centre . If radius of the disc is 10 cm and mu_(s) = (3)/(7) , then the angular speed at which the coin will just slip off at

A horizontal disc is rotating about a vertical axis passing through its centre. If an insect moves from centre to rim then the angular momentum of the system

A horizontal disc is rotating about a vertical axis passing through its centre. If an insect moves from centre to rim then the angular momentum of the system

A horizontal disc is rotating about a vertical axis passing through its centre. If an insect moves from centre to rim then the angular momentum of the system

Radius of gyration of disc rotating about an axis perpendicular to its plane passing through its centre is (If R is the radius of disc)

A coin kept on a horizontal rotating disc has its centre at a distance of 0.25 m from the axis of rotation of the disc. If mu is 0.2, then the angular velocity of the disc at which the coin willslip off, is

A coins kept on a horizontal rotating disc has its centre at a distance of 0.25 m from the axis of rotation of the disc .If mu is 0.2 , then the angular velocity of the disc at which the coion will slip off, (g=9.8m//s^(2))

A thin horizontal circular disc is rotating about a vertical axis passing through its centre. An insect is at rest at a point near the rim of the disc. The insect now moves along the diameter of the disc to reach its other end. During the journey of the insect. The angular speed of the disc:
