discs of mass in and 4m having radii of a and 2a respectively are rigidly fixed by a massless rigid rod of length 1 24a through their centres This assembly is laid on a firm and flat surface and set rolling without slipping on the surface so that the angular speed about the axis of the rod is wo The angular momentum of the entire assembly about the point O is I see the figure Which of the following statement s is are true JEE Adv 2016 4m O a b m 2a 0 The centre of mass of the assembly rotates about the z axis with an angular speed of co 5 The magnitude of angular momentum of center of mass of the assembly about the point O is 81 ma co c The magnitude of angular momentum of the assembly about its center of mass is 17 ma 2
