A particle of mass 200 MeV/c² collides with a
hydrogen atom at rest. Soon after the collision
the particle comes to rest, and the atom
recoils and goes to its first excited state. The
initial kinetic energy of the particle (in eV) is
. The value of N is :
(Given the mass of the hydrogen atom to be 1
GeV/c²) ______ .
