After absorbing a slowly moving neutron of massmN(momentum~0); a nucleus of massMbreaks into two nuclei of massesm1and5m1(6m1= M + mN), respectively. If the de-Broglie wavelength of the nucleus with massm1isλ, then de- Broglie wavelength of the other nucleus will be

Options:

Answer:
D
Solution:

de-Broglie wavelength λ=hmv=hp

Wherep= momentum

By conservation of momentum

P1+P2 =0

P1 = P2  ( not considering direction )
 λ1=λ2= λ
