Question

The mass of a helium atom (${}_{2}^{4}He$) is $4.0026	ext{ amu}$, while the masses of a free neutron and proton are $1.0087	ext{ amu}$ and $1.0078	ext{ amu}$ respectively. Assuming electron mass is negligible, what is the approximate binding energy per nucleon in the helium nucleus? (Given $1	ext{ amu} \approx 931.5	ext{ MeV}$)
