A ball is being rotated in a circle of radius 5 m with a constant tangential velocity of 20 m/s. A stone is also being rotated in a circle of radius 4 m with a constant tangential velocity of 16 m/s. Which one of the following choices is true about both the circular motions?
A. Both have same angular velocity
B. Both have different angular velocity
C. Angular velocity of ball > angular velocity of stone
D. Angular velocity of stone > angular velocity of ball
Answer:A
