(A) : A block of mass .m. rests on a wedge of mass M, which, in turn, is at rest on a horizontal table. All the surfaces are friction less. The block starts from rest. The position of c.m of the system will change only in vertical direction.(R ) : A block of mass .m. rests on a wedge of mass M, which, in turn, is at rest on a horizontal table. All the surfaces are friction less. The system is free from external force along horizontal direction.
