NEET Physics Time Period & Frequency MCQ Question

Type: MCQ-diagram based-Hard-Class 11

Consider a system where the displacement amplitude of an oscillator changes with angular frequency of the driving force as shown in a hypothetical figure based on the NCERT description. If the damping is small, what is the relationship between the driving frequency (ωd) and the natural frequency (ω) when the amplitude is maximum?

Question diagram
A

ωd / ω = 1

B

ωd / ω > 1

C

ωd / ω < 1

D

ωd = 0

Correct Answer

Option A

Detailed Explanation

The NCERT context states that the amplitude is greatest when the driving frequency (ωd) equals the natural frequency (ω), i.e., ωd / ω = 1.
