AP EAMCET · PHYSICS · Oscillations

A body of mass 4 kg attached to a spring of force constant \(64 \mathrm{~N} \mathrm{~m}^{-1}\) executes simple harmonic motion on a frictionless horizontal surface. The time period of oscillation is

  1. A \(\frac{\pi}{3} \mathrm{~s}\)
  2. B \(\frac{\pi}{2} \mathrm{~s}\)
  3. C \(\pi \mathrm{s}\)
  4. D \(\frac{3 \pi}{2} \mathrm{~s}\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(\frac{\pi}{2} \mathrm{~s}\)

Step-by-step Solution

Detailed explanation

\(T = 2\pi\sqrt{\frac{m}{k}}\) \(T = 2\pi\sqrt{\frac{4 \mathrm{~kg}}{64 \mathrm{~N} \mathrm{~m}^{-1}}}\) \(T = 2\pi\sqrt{\frac{1}{16}} \mathrm{~s}\) \(T = 2\pi \times \frac{1}{4} \mathrm{~s}\) \(T = \frac{\pi}{2} \mathrm{~s}\)
