A) 2
B) \[2\sqrt{2}\]
C) 4
D) 8
Correct Answer: B
Solution :
| [b] \[v=\sqrt{\frac{3RT}{M}}\Rightarrow \,\,\frac{{{V}_{x}}}{{{V}_{y}}}=\sqrt{\frac{{{M}_{y}}}{{{M}_{x}}}}\] |
| \[\Rightarrow \] \[=\frac{{{V}_{x}}}{{{V}_{y}}}=\sqrt{\frac{{{M}_{y}}}{8{{M}_{y}}}}\Rightarrow \,\,\frac{{{V}_{y}}}{{{V}_{x}}}=2\sqrt{2}\] |
