Question

The mass of proton, neutron and helium nucleus are respectively 1.0073 u, 1.0087 u and 4.0015 u. The binding energy of helium nucleus is: (A) 14.2 MeV (B) 7.1 MeV (C) 56.8 MeV (D) 28.4 MeV

Tardigrade Admin · Accepted Answer

B.E of Helium =(2 mP+2 mN-mH e) c2 =28.4 MeV

Q. The mass of proton, neutron and helium nucleus are respectively $1.0073 u$ , $1.0087 u$ and $4.0015 u$ . The binding energy of helium nucleus is:

$14.2 M e V$

$7.1 M e V$

$56.8 M e V$

$28.4 M e V$

B.E of Helium $= (2 m_{P} + 2 m_{N} - m_{He}) c^{2}$
$= 28.4 M e V$
