Question

A white dwarf star has volume V and contains N electrons so that the density of electron is \(n=\frac{N}{V}\). Taking the temperature of the star to be 0 K, what will be the expression for average energy per electron in the star?

• A. \(\frac{3h^2}{m}(3π^2n)^{3/2}\)
• B. \(\frac{3h^2}{10m}(3π^2n)^{2/3}\)
• C. \(\frac{h^2}{m}(3π^2n)^{2/3}\)
• D. \(\frac{3h^2}{10m}(3π^2n)^{1/3}\)
