A neutron moving with a speed `v` makes a head-on collision with a hydrogen in ground state kept at rest which inelastic collision will be take place is (assume that mass of photon is nearly equal to the mass of neutron)

A neutron moving with a speed v makes a head-on collision with a hydrogen atom in ground state kept at rest. Find the Minimum Kinetic Energy of Neutron for which inelastic collision will be take place is (assume that mass of h-atom is nearly equal to the mass of neutron)

A neutron moving with a speed , v makes a head on collosion with a hydrogen atom in atom in ground state which is at rest. Choose the correct options (s) of the following (assume mass of neutron is nearly equal to the mass of hydrogen atom) .

A neutron moving at a speed v undergoes a head-on elastic collision with a nucleus of mass number A at rest. The ratio of the kinetic energies of the neutron after and before collision is :
