Question

In the context of forced oscillations, what is resonance?
Options
A The phenomenon where the amplitude becomes very large when the driving force frequency is much lower than the natural frequency.
B The increase in amplitude near the natural frequency of the oscillating system.
Correct Answer
C The condition where the damping constant 'b' is equal to the angular frequency 'ω'.
D The phase shift between the driving force and the oscillation becomes π radians.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The text on page 24, under 'Resonance and Power Transfer', states: 'For small damping, the amplitude becomes very large when the frequency of the driving force is near the natural frequency ω₀ of the oscillating system. This increase in amplitude near ω₀ is called resonance. Hence ω₀ is also called resonance frequency of the system.'

Hint

Review the definition and characteristics of resonance in forced oscillations, as described on page 24.
