Show that the pressure exerted by a Fermi gas at absolute zero is
p = (2NEf)/(5V)
((If you need to use the relation for the mean energy <E> of particles obeying Fermi-Dirac statistics at absolute zero temperature, you can just quote it's <E> = 3Ef/5 I derived it earlier in this problem, so you don't have to derive it again))
In free electron theory , the electrons are considered as particles with half integral spins and so Fermions. The present problem describes the derivation of the pressure exerted by fermi gas at absolute zero.
