A uniform circular disc has radius R and mass m . A particle, also of mass m , if fixed at a point A on the edge of the disc as shown in the figure. The disc can rotate freely about a horizontal chord PQ that is at a distance R//4 from the centre C of the disc. The line AC is perpendicular to PQ . Initially the disc is held vertical with the point A at its highest position. it is then allowed to fall, so that it starts rotation about PQ. Find the linear speed of the particle as it reaches its lowest position.
