A) \[1/\sqrt{3}\]
B) \[\sqrt{3}\]
C) \[3\]
D) \[\frac{1}{3}\]
Correct Answer: B
Solution :
Kinetic energy \[{{k}_{2}}=15-10\,\,=\,\,5\,\,eV\] Tube \[KE\text{ }in\text{ }other\text{ }region\,\,=\,\,15\text{ }V.\] \[\frac{{{\lambda }_{1}}}{{{\lambda }_{2}}}\,\,=\,\,\sqrt{\frac{{{k}_{2}}}{{{k}_{1}}}}\,\,\Rightarrow \,\,\frac{{{\lambda }_{10V}}}{{{\lambda }_{0}}}\,\,\sqrt{\frac{15}{5}}\,\,=\,\,\sqrt{3}\]You need to login to perform this action.
