External forces

Vedclass · Answer

(B) The motion of the centre of mass of a system of particles is governed by the net external force acting on the system.According to Newton's second law for a system of particles,$F_{ext} = M A_{cm}$,where $F_{ext}$ is the sum of all external forces,$M$ is the total mass of the system,and $A_{cm}$ is the acceleration of the centre of mass.Internal forces cancel each other out due to Newton's third law and do not contribute to the acceleration of the centre of mass.Therefore,the centre of mass moves only under the influence of external forces.

Under which force the centre of mass is moving?
