A uniform circular disc has radius R and mass m A particle also of mass m is fixed at point A on the edge of the disc as shown in the Fig 2 38 The disc can rotate freely about a fixed horizontal R chord PQ which is at a distance 4 from the centre C of the disc The line AC is perpendicular to PQ Initially the disc is held vertical with point A as its highest point Find the linear speed of point A as it reaches its lowest position when the disc starts rotating about PQ P A m C R Fig 2 38 5gR
