A nucleusA,with a finite de-broglie wavelengthλA,undergoes spontaneous fission into two nucleiBandCof equal mass.Bflies in the same direction as that ofA,whileCflies in the opposite direction with a velocity equal to half of that ofB.The de-Broglie wavelengthsλB andλCof B and C are respectively:

Options:

Answer:
B
Solution:

hλA=hλB-hλC…(i)
AlsoλC=2λB...(ii)
From equation (i) & (ii),
1λA=1λB-12λB
λB=λA2;λC=λA
