Text Solution
Verified by ExpertsThe correct answer is:
B
de-Broglie wavelength associated with a moving particle can be given as
it thermal equilibrium, temperature of neutron and heavy water will be same.
This common temperature is given as, 
.
Kinetic energy of the neutron is 
de-Broglie wavelength of the neutron,
=
