A small mass m is attached to a massless string whose other end is fixed at P as shown in the figure. The mass is undergoing circular motion in the x-y plane with centre at O and constant angular speed ω. If the angular momentum of the system. calculated about O and P are denoted. by vacLO and vacP respectively, then.

A roller is made by joining together two cones at their vertices O. It is kept on two rails AB and CD which are placed asymmetrically(see figure), with its axis perpendicular to CD and its centre O at the centre of line joining AB and CD(see figure). It is given a light push so that it starts rolling with its centre O moving parallel to CD in the direction shown. As it moves, the roller will tend to.
