Spring Systems

S1S_1 and S2S_2 are two identical springs. The frequency of oscillation of mass m is F. If one spring is removed, the frequency will become

Show answer and solution

Answer: (d)

  1. On displacement xx, one spring stretches and the other compresses; both push back, so keff=2kk_{eff} = 2k.
  2. F=12π2kmF = \frac{1}{2\pi}\sqrt{\frac{2k}{m}}; with one spring F′=12πkmF' = \frac{1}{2\pi}\sqrt{\frac{k}{m}}.
  3. F′=F/2F' = F/\sqrt{2}, so the answer is (d).
