In figure, a hollow tube of mass 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 speed of B w.r.t M
(iii) Acceleration of centre of mass along X -axis is constant
(iv) Centre of mass has finite acceleration
Evaluate the above statements and choose the correct option from the following:
Options:
Answer:
C
Solution:
Momentum of the system in x-direction is conserved because all the forces on the system in xdirection are balanced. But the force in y-direction is not balanced. So, trajectory of motion of centre of the system is not constant.
