Certain stars at the end of their lives are thought to collapse, combining their protons and electrons together to form a neutron star. Such a star could be thought of as a giant atomic nucleus. If a star of mass equal to M = 4.00 1030 kg collapsed into neutrons (mn = 1.67 1027 kg), what would be the radius of such a star? (Hint: r = r0A1/3, where r0 = 1.20 1015 m.)
