The binding energies per nucleon for a d...

The binding energies per nucleon for a deuteron and an `alpha`-particle are `x_1 and x_2` respectively. The energy Q released in the reaction `""^2H_1 +""^2H_1 to ""^4He_2+Q` is

A

`(x_(1)+x_(2))`

B

`(x_(2)-x_(1))`

C

`4(x_(1)-x_(2))`

D

`4(x_(2)-x_(1))`

Text Solution

Verified by Experts

The correct Answer is:
D
`(4x1.0089+5x1.009)-9.012=Deltam`
binding energy `=Deltamxxc^(2)`
Bindng energy /nucleon `=("Binding energy")//9=6.72 MeV`
