Two H atoms in the ground state collide inelastically. The maximum amount by which their combined kinetic energy is reduced is (a) 10.20 eV (b) 20.40 eV (c) 13.6 eV (d) 27.2 eV
Correct option is A) Two atom initially at ground state. Now two atom collide inelastically. The total energy associate with the two atom is, =2×13.6=27.2eV The total energy associate with the two H-atom after collision, (13.6/2)2+13.6=17.0eV Hence, the maximum loss of their combined energy =27.2−17.0=10.2eV
