Question

A particle, with restoring force proportional to displacement and damping force proportional to velocity is subjected to a force F sin ωt. If the amplitude of the particle is maximum at ω = ω1 and its energy is maximum at ω = ω2, then (ω0 is the angular frequency of natural oscillations of the particle)

Solution

Correct option is

 

ω1 = ω0, ω2 = ω

In resonant oscillations, the amplitude and velocity (and hence energy) maxima occur when the angular frequency ω of the externally applied force equals the angular frequency ω0 of the natural oscillations.
