Question

In forced oscillations, a particle oscillates simple harmonically with a frequency equal to

• A. Frequency of driving force
• B. Natural frequency of body
• C. Difference in frequency of driving force and natural frequency
• D. Mean of frequency of driving force and natural frequency

Answer 1

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.
