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
5Ï€ rad s-1
D
10Ï€ rad s-1
Ask EduPadi AI for a detailed answer
Correct Option: D
Angular velocity w = 2Ï€ f.
But f = frequency no. of oscillations per second.
= 30/6 = 5Hz.
therefore W = 2Ï€ x 5
= 10Ï€ rad. s-1
