Question

A system consisting of several objects attached to each other. If the net external torque acting on the system is zero, then there will be

a) a change in the system's moment of inertia
b) no change in the system's moment of inertia
c) a change in the system's angular momentum about its center of mass
d) no change in the system's angular momentum about its center of mass

I personally think its D. Thanks

Answer 1

Answer: its D yea

Step-by-step explanation:

If the net external torque acting on the system is zero, the total angular momentum of a system remains constant, i.e. it is conserved
