A) double the initial value
B) half of the initial value
C) four times the initial value
D) ten times the initial value
E) \[\sqrt{(927/27)}\]
Correct Answer: B
Solution :
\[{{v}_{rms}}\propto \sqrt{T}\] \[\therefore \] \[\frac{v_{rms}^{}}{{{v}_{rms}}}=\sqrt{\left( \frac{T}{T} \right)}=\sqrt{\frac{300}{1200}}=\frac{1}{2}\] \[\Rightarrow \] \[v_{rms}^{}=\frac{{{v}_{rms}}}{2}\]You need to login to perform this action.
