Question

The ratio of angular velocities of two points A and B lying on two extreme ends of a sphere rotating with a constant angular velocity about the axis is .

• A. $\frac{\omega }{2}$
• B. ${\omega }^2$
• C. 1
• D. $\omega$

Answer 1

The correct option is C 1

Any point on a rigid rotating body has the same angular velocity. Therefore the points A and B have same angular velocities. And their ratio will be 1.
