d 4 1 A moving hydrogen atom makes a head on collision with a stationary hydrogen atom Before collision both atoms are in ground state and after collision they move together The minimum value of the kinetic energy of the moving hydrogen atom such that one of the atoms reaches of the excitation state is one a 20 4 eV c 54 4 eV b 10 2 eV d 13 6 eV
