After the Sun exhausts its nuclear fuel, its ultimate fate maybe to collapse to a white dwarf state. In this state, it would haveapproximately the same mass as it has now, but its radius would beequal to the radius of the Earth. (a) Calculate the average densityof the white dwarf.
(b) Calculate the surface free-fall acceleration
(c) Calculate the gravitational potential energy associated witha 2.04-kg object at the surface of the white dwarf.
