Angular momentum is conserved when:
A.Torque is constant
B.Net external torque is zero
C.Angular velocity is constant
D.The object is at rest
Explanation
Core Concept
Angular momentum (L = Iω) is conserved when the net external torque acting on a system is zero, analogous to how linear momentum is conserved when net external force is zero.
Correct Answer
BNet external torque is zero
