Question 2

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  10-27 kg), what would be the radius of such a star? (Hint: r = r0A1/3, where r0 = 1.20  10-15 m.)
 a. 12.7 km
  c. 16.1 km
  b. 25.4 km
  d. 18.5 km
