Question

The mass of proton is 1.0073 u and that of neutron is 1.0087 u (u = atomic mass unit). The binding energy of ⁴₂ He is

(Given helium nucleus mass = 4.0015 u.)

(a) 0.0305 J

(b) 0.0305 erg

(c) 28.4 MeV

(d) 0.061 u

Answer 1

The correct option is (c) 28.4 MeV.

Explanation:

= 931 x 0.0305 MeV = 28.4 MeV

(1 amu = 931 Mev).
