Question

A particle moving along circumference of circle subtends an angle of 30 at its centre in 2 seconds find angular velocity?

Answer 1

Answer:15 degree per second, i.e., π/12 radiun per second

Explanation:

Angular displacement(a) = 30 degree= π/6 radium

Time taken(t)= 2 second

Angular velocity=a/t=15 degree per second=π/12 radiun per second
