A particle executes simple harmonic motion between \(x =- A\) and \(x =+ A\). If time taken by particle to go from \(x=0\) to \(\frac{A}{2}\) is \(2 s\); then time taken by particle in going from \(x =\frac{ A }{2}\) to \(A\) is \(.........\,s\)
- A \(3\)
- B \(2\)
- C \(1.5\)
- D \(4\)
Answer & Solution
Correct Answer
(D) \(4\)
Step-by-step Solution
Detailed explanation
Let time from 0 to \(A / 2\) is \(t _1\) from \(A / 2\) to \(A\) is \(t _2\) then \(\omega t _1=\pi / 6\) \(\omega t _2=\pi / 3\) \(\frac{ t _1}{ t _2}=\frac{1}{2}\) \(t _2=2 t _1=2 \times 2=4\,sec\)
