Question

a damped mechanical oscillator of frequency w'o is acted uponby an external force of frequency w of natural frequency of undamped oscillations by omega not then the frequency of oscillation in steady state will be
1) wo
2) w'o
3) w
4) w-w'o

w is omeaga ​

Answer 1

NANBA..

If a frictional force (damping) proportional to the velocity is also present, the harmonic oscillator is described as a damped oscillator. Depending on the friction coefficient, the system can: Oscillate with a frequency lower than in the undamped case, and an amplitude decreasing with time (underdamped oscillator)...

Hope usefull...
