There are some passeger inside a stationary railway compartment. The centre of mass of the compartment itself (without the passngers) is `C_(1)` while the centre of mass of the compartment plus passengers system is `C_(2)` if passenger move about inside the comparment

There are some passengers inside a stationary railway compartment. The track is frictionless. The centre of mass of the compartment itself (without the passengers) is C_(1) , while the centre of mass of the 'compartment plus passengers' system is C_(2) . If the passengers move about inside the compartment along the track.

In a stationary railway compartment, there are several passengers. If they start moving in the compartment, will CM of the compartment change ? Will the CM of the system of compartment and passengers change ?

(A) : There are some passengers in a stastionary compartment. A physical fight takes place between them because of different opinions. The position of c.m of system will not change. (R ) : The fight between passengers is internal force.
