Hint -The law of conservation of Angular Momentum states that "When the net external torque acting on a system about a given axis is zero, the total angular momentum of the system about that axis remains constant." Complete step-by-step answer: The external torque on a body is zero, if the angular momentum of the body is conserved. The law of conservation of momentum states that in an isolated system the total momentum of two or more bodies acting upon each other remains constant unless an external force is applied. Therefore, momentum can neither be created nor destroyed. The law of conservation of momentum is based on which law of motion?.
