MCQ
In forced oscillations, a particle oscillates simple harmonically with frequency equal to
  • ✓
    Frequency of driving force
  • B
    Natural frequency of body
  • C
    Difference of frequency of driving and natural frequency
  • D
    Mean of driving force and natural frequency
✓

Answer

Correct option: A.
Frequency of driving force
a
(a)

The correct option is $A$ Frequency of driving force

In forced oscillation,we provide energy at the mean position, which helps the body to oscillate at a constant amplitude.It basically compensate the loss of energy which occur due to surrounding energy loss. A particle oscillates simple harmonically with a frequency equal to the frequency of driving force in steady state.
