1.	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» <P> Solution :Internal FORCES can not change the total or NET momentum of a system . Hence, the rate of change of total momentum of many PARTICLE system is proportional to the external force on the system `(Delta p = 0p = "CONSTANT")`
