A neutron having kinetic energy 12.5eV ...

A neutron having kinetic energy `12.5eV` collides with a hydrogen atom at rest negect the difference in mass between the neutron and the hydrogen atom and assume that the neutron does not leave its of motion find the posible kinetic energy of the neutron after the event

Text Solution

Verified by Experts

In one dimensional elastic collision of two bodies of equal masses, the initial velocities of bodies are interchanged after collision.
:. Velocity of the neutron after collision is zero. Hence, it has zero energy.
