Chapter 1, Problem 40AP

In a neutron star, gravity causes the electrons to combine with protons to form neutrons. A typical neutron star has a mass half that of the sun, compressed into a sphere of radius 20 km. If such a neutron star contains 6 .0 × 1 0 56 neutrons, calculate its density in grams per cubic centimeter. Compare this with the density inside a 232 Th nucleus, in which 142 neutrons and 90 protons occupy a sphere of radius 9 . 1 × 1 0 13 cm . Take the mass of a neutron to be 1 . 675 × 1 0 24 g and that of a proton to be 1 . 673 × 1 0 24 g .
