Given the following data: • Mass of proton

m_p = 1.00728\,\text{u}

• Mass of neutron

m_n = 1.00866\,\text{u}

• Experimental mass of

^{4}\mathrm{He}

nucleus

M = 4.00150\,\text{u}

•

1\,\text{u} = 931\,\text{MeV}

Find the binding energy per nucleon of

^{4}\mathrm{He}

(answer to two significant figures). (a)

7.4\,\text{MeV}

(b)

28.3\,\text{MeV}

(c)

7.1\,\text{MeV}

(d)

6.8\,\text{MeV}
