MHT CET · Physics · Oscillations
A mass x gram is suspended from a light spring. It is pulled in downward direction and released so that mass performs S.H.M. of period T. If mass is increased by \(Y\) gram, the period becomes \(4 T / 3\). The ratio of \(\mathrm{Y} / \mathrm{x}\) is
- A \(7: 9\)
- B \(5: 4\)
- C \(3: 2\)
- D \(8: 7\)
Answer & Solution
Correct Answer
(A) \(7: 9\)
Step-by-step Solution
Detailed explanation
\(T = 2\pi\sqrt{x/k}\) \(4T/3 = 2\pi\sqrt{(x+Y)/k}\)
