A) 1 : 3
B) 3 : 1
C) 1 : \[\sqrt{3}\]
D) \[\sqrt{3}\]: 1
Correct Answer: C
Solution :
The kinetic energy \[K=\frac{{{p}^{2}}}{2m}\] \[\frac{p_{1}^{2}}{2{{m}_{1}}}=\frac{p_{2}^{2}}{2{{m}_{2}}}\] \[\frac{{{p}_{1}}}{{{p}_{2}}}=\sqrt{\frac{{{m}_{1}}}{{{m}_{2}}}}=\sqrt{\frac{3}{1}}\] \[\frac{{{p}_{1}}}{{{p}_{2}}}=\frac{1}{\sqrt{3}}\]
