Statement-1 : The centre of mass of an isolated system is having some angular momentum which remains constant with time.
Statement-2 : The isolated system will not experience any net torque.
Options:
Answer:
A
Solution:
For an isolated system, external force and external torque are both zero, so its angular momentum stays constant. Statement-1 is true.
Statement-2 is also true: no external agent means no net external torque on the system.
Zero net torque is exactly why the angular momentum stays constant, so Statement-2 correctly explains Statement-1. Answer: A
