Question

If a simple harmonic oscillator has got a displacement of 0.02m and acceleration equal to 2m/s^2 at any time, the angular frequency of the oscillator is equal to ___________

(a) 10 rad/s

(b) 0.1 rad/s

(c) 100 rad/s

(d) 1 rad/s

The question was asked in an online interview.

My question is based upon Oscillations topic in division Oscillations of Engineering Physics I

Answer 1

The correct option is (a) 10 rad/s

The best explanation: a=-ω^2 y

ω^2=a/y=2/0.02=100

ω=10rad/s.
