Problem 1: White dwarf star
A white dwarf star is essentially a degenerate electron gas, with a bunch of nuclei mixed
in to balance the charge and to provide the gravitational attraction that holds the star
together. White dwarf stars tend to be extremely hot by our standards; nevertheless, it is
an excellent approximation in this problem to set T=0. The gravitational potential energy
inside a star of uniform density is Ugrav =
3 см2
a) Assuming that the star contains one proton and one neutron for each electron, and
that the electrons are nonrelativistic, show that the total (kinetic) energy of the
degenerate electrons equals
h²M³
Ukinetic = (0.0088)-
męm R?
b) The equilibrium radius of the white dwarf is that which minimize the total energy
Ugrav + Ukinetie: Sketch the total energy as a function of R, and find a formula for
the equilibrium radius in terms of the mass. As the mass increases, does the radius
increase or decrease? Does this make sense?
c) Evaluate the equilibrium radius…

An electron enters the region between them at a speed of 3.2 × 105 m/s by passing through a small hole in the negative plate and continues moving toward the positive plate. Assume the electric field between the plates is uniform.
