A) \[\frac{100\sqrt{2}}{3}\]
B) \[100\sqrt{2}\]
C) \[\frac{400}{\sqrt{3}}\]
D) None of these
Correct Answer: C
Solution :
Rms velocity doesnt depend upon pressure, it depends upon temperature only ie \[{{v}_{rms}}\propto \sqrt{T}.\] \[\Rightarrow \]\[\frac{{{v}_{1}}}{{{v}_{2}}}=\sqrt{\frac{{{T}_{1}}}{{{T}_{2}}}}\Rightarrow \frac{200}{{{v}_{2}}}=\sqrt{\frac{(273+27)}{(273+127)}}=\sqrt{\frac{300}{400}}\] \[\Rightarrow \] \[{{v}_{2}}=\frac{400}{\sqrt{3}}m/s\]You need to login to perform this action.
