Angular velocity is always directed perpendicular to the plane of the circular path. Hence, required change in angle = 0°

Q. 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?

$0^{\circ}$

$4 5^{\circ}$

$18 0^{\circ}$

$36 0^{\circ}$

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