AP EAMCET · PHYSICS · Oscillations
If the amplitude of a lightly damped oscillator decreases by \(1.5 \%\) then the mechanical energy of the oscillator lost in each cycle is
- A \(1.5 \%\)
- B \(0.75 \%\)
- C \(6 \%\)
- D \(3 \%\)
Answer & Solution
Correct Answer
(D) \(3 \%\)
Step-by-step Solution
Detailed explanation
We know that, mechanical energy of oscillator lost in each cycle is proportional to the square of amplitude \((A)\). Then fractional change in energy \(\frac{\Delta E}{E} \simeq \frac{d E}{E}=\frac{d A^2}{A^2}\)…
