The mass of proton is `1.0073 u` and that of neutron is `1.0087 u` (`u=` atomic mass unit). The binding energy of `._(2)He^(4)` is (mass of helium nucleus `=4.0015 u`)

`0.0305 J`

`0.0305 erg`

`28.4 MeV`

`0.061 u`

Text Solution

Verified by Experts

The correct Answer is:

`._(2)^(4)He -= 2n + p`
`BE = [2(1.0073 + 1.0087) - 4 .0015]931.5MeV`
