A) \[\frac{{{m}_{e}}}{{{m}_{p}}}\]
B) \[\sqrt{\frac{{{m}_{e}}}{{{m}_{p}}}}\]
C) \[\frac{{{m}_{p}}}{{{m}_{e}}}\]
D) \[\sqrt{\frac{{{m}_{p}}}{{{m}_{e}}}}\]
Correct Answer: A
Solution :
Linear momentum of electron,\[{{p}_{e}}=\sqrt{2{{m}_{e}}eV}\] Linear momentum of photon, \[{{p}_{p}}=\sqrt{2{{m}_{p}}eV}\] \[\frac{{{p}_{e}}}{{{p}_{p}}}=\frac{\sqrt{2{{m}_{e}}eV}}{\sqrt{2{{m}_{p}}eV}}\] \[\frac{{{p}_{e}}}{{{p}_{p}}}=\sqrt{\frac{{{m}_{e}}}{{{m}_{p}}}}\]
