Question on: JAMB Physics - 2002
A particle in circular motion performs 30 oscillation in 6 seconds. Its angular velocity is
A
5 rad s-1
B
6 rad s-1
C
5π rad s-1
D
10π rad s-1
Ask EduPadi AI for a detailed answer
Correct Option: D
Angular velocity w = 2π f.
But f = frequency no. of oscillations per second.
= 30/6 = 5Hz.<br />
therefore W = 2π x 5
= 10π rad. s<sup>-1</sup>
