Consider the following two equations
(A) L = Iω
(B) dL/dt = T In noninertial frames (a) both A and B are true
(b) A is true but B is false
(c) B is true but A is false
(d) both A and B are false
Explanation:
dL/dt = total torque of external force, not equal to any torque.
So dL/dt = Γ is not correct.
