A block has undamped natural angular frequency ω₁. With weak damping it oscillates freely at angular frequency ω₂. Under sinusoidal forcing with damping, displacement amplitude is maximum at angular frequency ω₃. Which relation is correct?

Question

G1 Physics · Accepted Answer

For damping, free frequency is slightly below ω₁ and displacement-resonance frequency is lower still. Thus ω₁>ω₂>ω₃. Hence A.
