A nucleus A, With a finite de-broglie wavelength `lambda_(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 wavelength `lambda_(B)` and `lambda_(c)` of B and C are respectively:

A

`lambda_(A), 2lambda_(A)`

B

`(lambda_(A))/(2), lambda_(A)`

C

`lambda_(A), (lambda_(A))/(2)`
