Question

A neutron travelling with a velocity v and kinetic energy E
has a perfectly elastic head-on collision with a nucleus of
an atom of mass number A at rest. The fraction of total
energy retained by the neutron is approximately
(a) [(A – 1)/(A + 1)]² (b) [(A + 1)/(A – 1)]²
(c) [(A – 1)/A]² (d) [(A + 1)/A]²
