A) \[100\sqrt{2}\]
B) \[\frac{400}{\sqrt{3}}\]
C) \[\frac{100\sqrt{2}}{3}\]
D) \[\frac{100}{3}\]
Correct Answer: B
Solution :
\[v\propto \sqrt{T}\Rightarrow \frac{v}{200}=\sqrt{\frac{400}{300}}\Rightarrow v=\frac{200\times 2}{\sqrt{3}}\,\,m/s\]\[\Rightarrow \] \[v=\frac{400}{\sqrt{3}}\,m/s\]You need to login to perform this action.
