A) \[2{{v}_{0}}\]
B) \[4{{v}_{0}}\]
C) \[{{v}_{0}}/2\]
D) \[{{v}_{0}}/4\]
Correct Answer: B
Solution :
\[v\propto {{Z}^{2}}\Rightarrow \frac{{{v}_{{{H}_{2}}}}}{{{v}_{He}}}={{\left( \frac{1}{2} \right)}^{2}}=\frac{1}{4}\] \[\Rightarrow \]\[{{v}_{He}}=4{{v}_{{{H}_{2}}}}=4{{v}_{0}}\]You need to login to perform this action.
