If a simple harmonic oscillator has got a displacement of 0.02 m and acceleration equal to 2.0 m/s² 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

Answer: (a). |a| = ω² x ω² = (2.0)/(0.02) = 100 ⇒ ω = 10 rad/s So the answer is (a) 10 rad/s.

Velocity & Acceleration in SHM

If a simple harmonic oscillator has got a displacement of $0.02\text{ m}$ and acceleration equal to $2.0\text{ m/s}^2$ at any time, the angular frequency of the oscillator is equal to

Show answer and solution

Answer: (a)

$|a| = \omega^2 x$
$\omega^2 = \frac{2.0}{0.02} = 100 \Rightarrow \omega = 10$ rad/s
So the answer is (a) 10 rad/s.
