The binding energies per nucleon for deuteron (`._1H^2`) and helium (`._2He^4)` are `1.1 MeV` and `7.0 MeV` respectively. The energy released when two deutrons fuse to form a helium nucleus (`._2He^4`) is……..

Text Solution

Verified by Experts

`._1^2H +._1^2H rarr ._2^4He`
Binding energy of two deutrons is
`2[1.10020 xx2]=4.4 MeV`
Binding energy of one helium `=4xx7=2.8 MeV`
The energy released `=28-4.4 =23.6 MeV`.
