NEET Physics MCQ: NCERT Center of Mass Motion

A dog of mass $m$ stands at one end of a flat boat of mass $M$ and length $L$ at rest on a frictionless surface of a lake. The dog walks to the other end of the boat and stops. The displacement of the center of mass of the boat-dog system is:

$mL/(M+m)$

$ML/(M+m)$

$mL/M$
