A) \[(\sqrt{10})\]
B) \[(\sqrt{5})\]
C) \[\left( \sqrt{\frac{10}{\pi }} \right)\]
D) \[\left( \frac{\sqrt{5}}{\pi } \right)\]
Correct Answer: D
Solution :
[d] \[F=-\frac{dU}{dx}=-20x\] \[a=\frac{F}{M}=\frac{-20x}{1}=-20x\] \[-20x=-{{\omega }^{2}}(x)\] \[\therefore \,\,\,\omega =\sqrt{20}=2\sqrt{5}\] \[f=\frac{\omega }{2\pi }=\frac{2\sqrt{5}}{2\pi }=\left( \frac{\sqrt{5}}{\pi } \right)\]You need to login to perform this action.
