Question

If a neutron star and a white dwarf has a total mass of 1M. If the white
dwarf has a radius of 9 x 10⁶ m and the neutron star has a radius of 11 km.
i) Compare the surface gravity of both stars.
ii) What is the density of the neutron star?
iii) Assuming the neutron star is entirely made up of neutrons, and that the
interparticle separation of a gas of density n is l = n^-1/3. How far apart are the
neutrons from each other?
