Answer: rad/s.
- A rad/s
- B rev/s
- C deg/s
- D m/s
Correct answer: A. rad/s
Explanation: Angular velocity is measured in radians per second (rad/s). It is related to frequency by ω = 2πf.
Torque about axis O equals the force F multiplied by the perpendicular distance r⊥ from the axis to the line of action of the force, producing rotation.
Concept context
Moment of inertia, torque, angular momentum, rolling motion. Very high JEE weightage.
