    There are 100 passengers in a stationary railway compartment. A physical fight starts between the passengers over some difference of opinion, (i) Will the position of CM of the compartment change? (ii) Will the position of CM of system (compartment +100 passengers) change? Give reason.

    Answer:

                     (i) The position of the CM of the compartment will change because the passengers are external bodies for the compartment. (ii) The position of CM of the system will not change as no external force is acting on the system.
