Underline the correct alternative:

(c) The rate of change of total momentum of a many-particle system is proportional to the external force/sum of the internal forces on the system.

Answer

External force
Internal forces cannot produce any change in the total momentum of a body, irrespective of the direction. Hence, the total momentum of a many- particle system is proportional to the external forces acting on the system.
