A) Two
B) Three
C) Six
D) Four
Correct Answer: D
Solution :
[d] r.m.s. velocity \[{{V}_{rms}}=\sqrt{\frac{3RT}{M}}\] i.e., \[\frac{{{V}_{1}}}{{{V}_{2}}}=\sqrt{\frac{{{T}_{1}}}{{{T}_{2}}}}\] \[\frac{5\times {{10}^{4}}}{10\times {{10}^{4}}}=\frac{1}{2}=\sqrt{\frac{{{T}_{1}}}{{{T}_{2}}}}\] \[\therefore {{T}_{2}}=4{{T}_{1}}\]You need to login to perform this action.
