  1. A f
  2. B 2 f
  3. C \(\frac{\mathrm{f}}{\sqrt{2}}\)
  4. D \(\sqrt{2} \cdot \mathrm{f}\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(\frac{\mathrm{f}}{\sqrt{2}}\)

Step-by-step Solution

Detailed explanation

Springs in parallel: \(K_{eq1} = K + K = 2K\) Initial frequency: \(f = \frac{1}{2\pi} \sqrt{\frac{K_{eq1}}{m}} = \frac{1}{2\pi} \sqrt{\frac{2K}{m}}\)
