A disc of radius R is hinged at its centre such that it lies in a horizontal plane It rotates about the hinge with a constant angular velocity w A coin of mass m is placed at a distance of r from the centre The limiting value of angular velocity such that coin does not slip over the disc us coefficient of static friction pk coefficient of kinetic friction O g 9 9 r
