Question

3. A particle is moving along circular path of radius r.
When it completes semi-circular path, then by
what angle its angular velocity changes?
(1) 0°
(2) 45°
(3) 180°
(4) 360°​

Answer 1

when a particle moves along a semicircular path its angular velocity remains constant so it does not contain any angle and theta is equals to zero degree

Answer 2

Answer:

Correct option is (a)

Explanation:

Since we know that whenever the body perform the a circular motion its angular velocity is function of linear velocity and radius of circular path.

$v=r\varpi$

where v=linear velocity, r=radius of circular path, ω=angualr velocity.

since r is constant for circular path, so angular velocity remains constant.

It does not change with respect to angle.

so correct option is (a)
