AP EAMCET · PHYSICS · Oscillations
An object of mass \(3 \mathrm{~kg}\) is executing simple harmonic motion with an amplitude \(\frac{2}{\pi} \mathrm{m}\). If the kinetic energy of the object when it crosses the mean position is \(6 \mathrm{~J}\), the time period of oscillation of the object is
- A \(1 \mathrm{~s}\)
- B \(2 \mathrm{~s}\)
- C \(3 \mathrm{~s}\)
- D \(4 \mathrm{~s}\)
Answer & Solution
Correct Answer
(B) \(2 \mathrm{~s}\)
Step-by-step Solution
Detailed explanation
Mass of object, \(\mathrm{m}=3 \mathrm{~kg}\) Amplitude, \(A=\frac{2}{\pi} \mathrm{m}\) Kinetic energy \(=6 \mathrm{~J}\) Kinetic energy \(=\frac{1}{2} m \omega^2 A^2=6\)…
