Prove That The Total External Torque Acting On A System Of Particles Is Equal To The Time Rate Of Angular Momentum Of The System, Provided That The Internal Forces Between The Particles Are Central Forces (i.e., The Internal Forces Between Any Two Particles Are Always Directed Along The Line Joining The Particles).

Relation between angular momentum and total external torque: Let us consider be the resultant external force acting on the ith particle of a system of n particles and be the…
