At the end of its life, a star with a mass 7.8 times the Sun's mass is expected to collapse,
combining its protons and electrons to form a neutron star. Such a star could be thought of as
a gigantic atomic nucleus. If a star of mass 7.8 x 1.99 x 1030 kg collapsed into neutrons
(m, = 1.67 x 10-27 kg), what would its radius be? Assume that r = rA/3.
