A body of mass \(0.01\;kg\) executes simple harmonic motion (S.H.M.) about \(x=0\) under the influence of a force shown below: The period of the S.H.M. is
1 \(0.52\;s\)
2 \(1.05\;s\)
3 \(0.30\;s\)
4 \(0.25\;s\)
Explanation:
From graph, slope \(K=\dfrac{F}{x}=\dfrac{8}{2}=4\) \(T = 2\pi \sqrt {\frac{m}{K}} \Rightarrow T = 2\pi \sqrt {\frac{{0.01}}{4}} = 0.3\;s.\)
