Question

A particle is moving along a circular path with uniform speed. Through what angle does its angular velocity change when it completes half of the circular path?

• A. $0^{\circ }$
• B. ${45}^{\circ }$
• C. ${180}^{\circ }$
• D. ${360}^{\circ }$

Answer 1

The correct option is A $0^{\circ }$

Angular velocity is always directed perpendicular to the plane of the circular motion.
Hence, change in angle is $0^{\circ }$
