A) \[100\sqrt{2}\]
B) \[\frac{400}{\sqrt{3}}\]
C) \[\frac{100\sqrt{2}}{3}\]
D) \[\frac{100}{3}\]
Correct Answer: B
Solution :
[b] Here \[{{v}_{1}}=200\text{ }m/s;\] temperature \[{{T}_{1}}=27{}^\circ C=27+273=300k\] temperature \[{{T}_{2}}=127{}^\circ C=127+273=400k,\] V=? R.M.S. Velocity, \[V\propto \sqrt{T}\] \[\Rightarrow \frac{v}{200}=\sqrt{\frac{400}{300}}\Rightarrow v=\frac{400}{\sqrt{3}}m/s\]You need to login to perform this action.
