A nucleus A, with a finite de-broglie wavelength λ A , undergoes spontaneous fission into two nuclei B and C of equal mass. B flies in the same direction as that of A, while C flies in the opposite direction with a velocity equal to half of that of B. The de-broglie wavelengths λ B and λ C of B and C are respectively -

1. 2 , A A λ λ
2. λ A , 2 λ A
3. 2 λ A , λ A
4. A A , 2 λ λ

Correct answer: A A , 2 λ λ
