Spring Systems

If the period of a oscillation of mass ' m ' suspended from a spring is 2 s, then the period of suspended mass ' 4 m ' with the same spring will be

Show answer and solution

Answer: (d)

  1. T=2πm/k⇒T∝mT = 2\pi\sqrt{m/k} \Rightarrow T \propto \sqrt{m}.
  2. T′=24=4 sT' = 2\sqrt{4} = 4\text{ s}.
  3. So the answer is (d) 4 s.
