For a 1 solar mass white dwarf with a radius of 6000km, calculate the momentum and kinetic energy (in units of electronvolts) of an electron in the highest occupied electron state. Assume the star consists only of carbon and has a uniform density. Calculate the momentum and kinetic energy of a neutron in the highest occupied neutron state for a 2 solar mass neutron star with a radius of 1Okm.
