Assertion Reason Questions on System of Particles and Rotational Motion
Assertion Reason Questions
Directions:
Each of the following questions consists of two statements: an Assertion (A) and a Reason (R). Answer them by selecting the correct option:
(a) Both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).
(b) Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
(c) Assertion (A) is true, but Reason (R) is false.
(d) Assertion (A) is false, but Reason (R) is true.
Q1. Assertion (A): The center of mass of a uniform semicircular ring lies at its geometric center.
Reason (R): The center of mass always lies at the center of the figure.
Answer: (c) Assertion is false, but Reason is true.
Difficulty Level: Tough
Q2. Assertion (A): A body can rotate even if its center of mass remains at rest.
Reason (R): Torque causes rotational motion, independent of translational motion.
Answer: (a) Both A and R are true, and R is the correct explanation of A.
Difficulty Level: Moderate
Q3. Assertion (A): Moment of inertia depends on the distribution of mass and the axis of rotation.
Reason (R): Moment of inertia is a scalar quantity.
Answer: (c) Assertion is true, but Reason is false.
Difficulty Level: Moderate
Q4. Assertion (A): Angular momentum of a system is conserved in the absence of external torque.
Reason (R): Torque is the time derivative of angular momentum.
Answer: (a) Both A and R are true, and R is the correct explanation of A.
Difficulty Level: Moderate
Q5. Assertion (A): The radius of gyration of a body is equal to the distance of its center of mass from the axis of rotation.
Reason (R): Radius of gyration is defined as the distance from axis at which mass may be assumed to be concentrated.
Answer: (b) Both A and R are true, but R is not the correct explanation of A.
Difficulty Level: Tough
