Calculate the mass of an alpha-particle....

Calculate the mass of an `alpha-particle.Its binding energy is 28.2 meV.

Text Solution

Verified by Experts

The correct Answer is:
A, D
Let the mass of `'alpha'` particle be xu
`'alpha'` particle contains 2 protons and 2
neutrons
`:. Binding Energy`
`=(2 xx 1.007825 xx 1.00866u - xu) c^2`
`=28.2 MeV (given)`
`x = 4.0016 u` .
