A) \[0.1\text{ }m{{s}^{-1}}\]
B) \[10\text{ }m{{s}^{-1}}\]
C) \[100\text{ }m{{s}^{-1}}\]
D) \[1000\text{ }m{{s}^{-1}}\]
Correct Answer: D
Solution :
The given equation comparing with standard equation \[y=A\sin \frac{2\pi }{\lambda }(vt-x)\] \[\therefore \] \[\frac{2\pi }{\lambda }v=100\]and \[\frac{2\pi }{\lambda }=\frac{1}{10}\] \[\Rightarrow \] \[v=1000\text{ }m{{s}^{-1}}\]
