Two hydrogen like atoms `A` and `B` having `(N)/(Z)` ratio equal to 1 have atomic number `Z_(A)` and `Z_(B)` A is moving, while `B` is stationary and both are in ground state. The minimum kinetic energy which `A` must have to have an inelastic collision with B such that both `A` and `B` getting excited is `221 e V`. If situation is reversed and B is made to stike `A` which is stationary and both in ground state then minimum kinetic energy which B must have to make an inelastic coliision with both getting excited is `331.5 e V`. Assume mase of proton = mass of neutron. The atomic formula of`A` and `B` are :-
