Kinematics of Circular Motion: Practice Problem & Solution
Assertion (A): Infinitesimally small angular displacement is a vector quantity. Reason (R): Angular velocity doesn't depend upon reference frame.
Short Solution (Best for NEET):
To solve this problem, we apply the core principles of Kinematics of Circular Motion. Understanding the underlying formula is key to arriving at the correct answer below:
Infinitesimally small angular displacement \( d\vec{\theta} \) is a vector because it obeys the commutative law of vector addition. Thus (A) is true.
Angular velocity \( \vec{\omega} \) is a vector quantity, and its value depends on the chosen reference frame. Hence (R) is false.
