A neutron moving with a speed of 10^6 ms^(-1) suffers a head - on collision with a nucleus of mass number 80. What is the fraction of energy retained by the neutron?

A neutron with velocity v suffers head on elastic collision with the nucleus of an atom of mass number A at rest. The fraction of energy retained by neutron is

A neutron travelling with a velocity collides elastically, head on, with a nucleus of an atom of mass number A at rest. The fraction of total energy retained by neutron is

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 :

A neutron travelling with a velocity v and kinetic energy E collides elastically head on with the nucleus of an atom of mass number A at rest. The fraction of total energy retained by the neutron is :

A ball of mass in moving with speed u undergoes a head-on elastic collision with a ball of mass nm initially at rest. The fraction of the incident energy transferred to the second ball is

A neutron collides head-on and elasticity with an atom of mass number A , which is initially at rest. The fraction of kinetic energy retained by neutron is
