The angular speed `omega ` is given by

A rough disc of mass m rotates freely with an angular velocity omega . If another rough disc of mass m/2 and same radius but spinning in opposite sense with angular speed omega is kept on the first disc. Then:

A particle of mass m rotates with a uniform angular speed omega . It is viewed from a frame rotating about the Z-axis with a uniform angular speed omega_0 . The centrifugal force on the particler is
