NEET Physics Damped & Forced Oscillations MCQ Question

Type: MCQ-numerical-Hard-Class 11

A damped oscillator has a damping constant b and mass m. If the damping is small, which of the following expressions approximates the angular frequency of the damped oscillator?

A

ω = √(k/m)

B

ω' = √(k/m - (b^2/4m^2))

C

ω' = ω - (b/2m)

D

ω' ≈ ω

Correct Answer

Option D

Detailed Explanation

The NCERT context states that if the damping constant is small, the angular frequency of the damped oscillator (ω') is approximately equal to the natural angular frequency (ω) of the undamped system.
