Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): When no external torque acts on a body, its angular velocity remains constant as long as moment of inertia is constant.
Reason (R): Torque \(\tau=0 ; \frac{d L}{d t}=0\), L = constant.
L = Iω = constant
In the light of the above statements, choose the most appropriate answer from the options given below:
- (A) is true but (R) is false
- (A) is false but (R) is true
- Both (A) and (R) are true and (R) is the correct explanation of (A)
- Both (A) and (R) are true and (R) is not the correct explanation of (A)
Answer
(C) Both (A) and (R) are true and (R) is the correct explanation of (A)
