Question: In a neutron star, all the mass has collapsed into a relatively small volume. (a) If a particular neutron star has a radius of 1000

In a neutron star, all the mass has “collapsed” into a relatively small volume. 

(a) If a particular neutron star has a radius of 1000 m and a mass of 2.0 × 1028 kg, what is its density? 

(b) Compare this value with the density of the Sun and with the density of steel.
