A particle moves in xy plane on a circular path of radius 10 m (with centre at origin) with constant speed 20 m/s. Its velocity vector at point (0, 10 m) if it's angular velocity its along z-axis is :
Answer & explanation
Correct answer: option 3
The right hand thumb rule states that if we wrap our right hand fingers in the sense of turning, the direction of thumb gives the direction of angular velocity.
