NEET Physics Damped & Forced Oscillations Assertion Reason Question
Assertion (A): In a damped oscillating system, the angular frequency of the damped oscillator is approximately equal to the natural frequency if the damping constant is small. | Reason (R): The damping force in such a system is proportional to the velocity of the oscillator.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false, but R is true.
Correct Answer
Detailed Explanation
Both the assertion and reason are true. 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 frequency (ω), and the damping force is given as Fd = -bv, proportional to velocity.
