A) \[{{\lambda }_{p}}<{{\lambda }_{e}}\]
B) \[{{\lambda }_{p}}>{{\lambda }_{e}}\]
C) \[{{\lambda }_{p}}={{\lambda }_{e}}\]
D) \[{{\lambda }_{p}}=2{{\lambda }_{e}}\]
Correct Answer: A
Solution :
By using \[\lambda =\frac{h}{\sqrt{2mE}}\] E = 10?32 J = Constant for both particles. Hence \[\lambda \propto \frac{1}{\sqrt{m}}\] Since \[{{m}_{p}}>{{m}_{e}}\] so \[{{\lambda }_{p}}<{{\lambda }_{e}}.\]
