A) \[\sqrt{\frac{4}{3}}\]
B) \[\sqrt{\frac{8}{3}}\]
C) \[\sqrt{\frac{3}{8}}\]
D) \[\sqrt{\frac{2}{4}}\]
Correct Answer: B
Solution :
de - Broglie wavelength is given by \[\lambda =\frac{h}{\sqrt{3m\,KT}}\] \[\frac{\lambda {{H}_{2}}}{\lambda {{H}_{e}}}=\sqrt{\frac{{{m}_{He}}{{T}_{He}}}{{{m}_{{{H}_{2}}}}{{T}_{{{H}_{2}}}}}}=\sqrt{\frac{8}{3}}\]You need to login to perform this action.
