Question

Ques-13 If a body is moving with a constant speed of 10/sec in a circular path of radius 2m the
angular velocity of the body is:
(a) 5 red/sec (b) 2 red/sec (c) 10 red/ sec (d) 7.5 red/sec​

Answer 1

Answer :-

Given :-

• Linear velocity = 10 m/s
• Radius = 2 m

To Find :-

• Angular velocity of body

Solution :-

Relationship between linear velocity and angular velocity :-

→ ω = v/r

where -

• ω is angular velocity
• v is linear velocity
• r is radius of the circle

Substituting the values in formula :-

→ Angular velocity = 10 / 2

→ ω = 5

Angular velocity = 5 rad/s
