After absorbing a slowly moving neutron of Mass m_(N) (momentum ~~0 ) a nucleus of mass M breaks into two nuclei of masses m_(1)and5m_(1) (6m_(1)=M+m_(N)) respectively. If the de Broglie wavelength of the nucleus with mass m_(1) is lamda the de Broglie wavelength of the nucleus will be

SOLUTION :`P=0`
`P_(1)=P+P_(2)`
`P_(1)=P_(2)`
`0+P_(1)+P_(2)`
`(P_(1)=-P_(2))`
`lambda_(1)=(H)/(P_(1))`
`lambda_(2)=(h)/(P_(2))`
`|lambda_(1)|=|lambda_(2)|`
`lambda_(1)=lambda_(2)`
