True or False Statements :
In the nuclear reaction `X^(200) rarr A ^(110)+B^(90)`. If the binding energy per nucleon for X, A and B is 7.4 MeV, 8.2.MeV and 8.2 MeV respectively, the energy released is 160 MeV.

Text Solution

Verified by Experts

The correct Answer is:
[T]
`DeltaE=E(B.E.)_(P)-E(B.E.)_(R)`
`rArr (110xx8.2+90xx8.2)-(200xx7.4)=160` MeV
