Find the binding energy of an a-particle from the following data :
Mass of He nucleus = 4.001256 amu
Mass of proton = 1.007277amu
Mass of neutron = 1.00866 amu
(Take one amu = 931.5 MeV)
A
1850 MeV
B
296 MeV
C
28.512 MeV
D
None
Answer
28.512 MeV
Explanation
Solution
Dm = (2 × mp + 2mn) – Mn
= [(2 × 1.007277) + (2 × 1.00866)] – (4.001265)
BE = DE = Dm × 931 MeV
