Question

A particle is moving with uniform speed 0.5 m/s
along a circle of radius 1m then the angular
velocity of particle is
1) 2 rad s-' 2) 1.5 rad s
3) 1 rad s ' 4) 0.5 rad s-​

Answer 1

Answer:

4

Explanation:

angular velocity. =angular displacement/total time taken

Answer 2

Answer:

A particle is moving with a uniform speed of 0.5 m/s  along a circle of radius 1m then the angular  velocity of the particle is 0.5 rad/sec

Explanation:

• In a circular motion, the linear velocity (V) and angular velocity (w) are related as,

        $V=rw$

        where r-radius of the circular path

From the question,

the radius of the circular path $r=1m$

the speed of the particle $v=0.5m/s$

rearrange the above equation to get the angular velocity of the particle,$w=v/r$

⇒ $w=0.5/1=0.5rad/sec$

option D is the right answer
