Question

Consider the following two equations

(A) L = l ω

(B) dL/dt = Γ

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.

Answer 1

(b) A is true but B is false

Explanation: 

dL/dt = total torque of external force, not equal to any torque. 

So dL/dt = Γ is not correct.
