A) \[2.56\times {{10}^{3}}m/s\]
B) \[2.98\times {{10}^{5}}m/s\]
C) \[3.33\times {{10}^{7}}m/s\]
D) \[5.01\times {{10}^{9}}m/s\]
Correct Answer: C
Solution :
According to law of conservation of momentum. Momentum of neutron = Momentum of combination Þ\[1.67\times {{10}^{-27}}\times {{10}^{8}}=(1.67\times {{10}^{-27}}+3.34\times {{10}^{-27}})\ v\] \\[v=3.33\times {{10}^{7}}\,m/s\]
