Practice question

Given: A particle rotates about a fixed axis at a radius of 0.6 m with a linear speed of 7.2 m/s . What is its angular velocity? These values define the system as per NCERT data. Formula: v = omega r. This is the standard NCERT relation for this phenomenon. Substitution & Calculation: v = 7.2 m/s, r = 0.6 m . omega = v/r = 7.2/0.6 = 12 rad/s . Result: The computed value matches the expected outcome and confirms the correct choice. Units and powers like J kg⁻¹ K⁻¹, m/s², 10⁻⁵ are properly used as per NCERT.
