Question
Q452) An electron moving with velocity 'v' is found to have a certain value of de-broglie wave length. the velocity to be possessed by the neutron to have the same de-Broglie wave length is ...



SOLUTION

mass of neutron=1840× mass of electron
for equal wavelengths momentum of neutron=momentum of electron
&therefore vn × 1840(m)=v×m
vn=v/1840
Answer: (c)
