The binding energy per nucleon of deuter...

The binding energy per nucleon of deuterium and helium atom is `1.1 MeV` and `7.0 MeV`. If two deuterium nuclei fuse to form helium atom, the energy released is.

19.2 MeV

23.6 MeV

26.9 MeV

13.9 MeV

Text Solution

Verified by Experts

The correct Answer is:

`""_(1)^(2) H + ""_(1)^(2) H rarr ""_(2)^(4) He` + energy
energy released `= (4 xx 7 - 4 xx 1.1) MeV`= 23.6 MeV
