In Fig., a hollow tube of mass M is free in horizontal direction. The system is released from rest. There is no friction present. The tube and blocks are taken as system. i. Momentum of the system is conserved in x-direction. ii. Speed of A w.r.t. M= speed of B w.r.t. M. iii. Trajectory of centre of mass is X-constant. iv. Centre of mass has finite acceleration. Evaluate the above statements and choose the correct option from the following:
