A particle in circular motion performs 30 oscillation in 6 seconds. Its angular velocity is
- 5 rad s-1
- 6 rad s-1
- 5π rad s-1
-
10π rad s-1
The correct answer is: D
Explanation
Angular velocity w = 2π f.But f = frequency no. of oscillations per second.
= 30/6 = 5Hz.
therefore W = 2π x 5
= 10π rad. s-1
