NEET Physics Damped & Forced Oscillations MCQ Question
A diagram shows a damped harmonic oscillator with a mass attached to a spring moving horizontally on a surface with a damping force F_d = -bv. Which of the following correctly describes the effect of damping on the angular frequency of the oscillator?
The angular frequency decreases and becomes ω' = √(ω² - (b/2m)²).
The angular frequency remains constant regardless of damping.
The angular frequency increases with more damping.
The angular frequency is independent of mass.
Correct Answer
Detailed Explanation
The NCERT context explains that for a damped oscillator, the angular frequency ω' is given by ω' = √(ω² - (b/2m)²), indicating a decrease due to damping.
