In this exercise we want to calculate the linear density of a computer, in this way we find that:
A)[tex][100]=0.3536 atoms[/tex]
B)[tex][111]=0.204 atoms[/tex]
So calculating the diagonal of a square we have:
[tex]D(d)= 4R\\d^2=a^2+a^2\\d=a\sqrt 2\\a=2\sqrt 2R[/tex]
A)Now doing the calculation of the atoms along the bar [100] we have:
[tex]AL= 1/2\sqrt2R\\=1/2\sqrt2\\=0,3536 atms[/tex]
B)Now doing the calculation of the atoms along the bar [111] we have:
[tex]AL= 1/2\sqrt3R\\=1/2\sqrt2*\sqrt3\\=1/2\sqrt6\\=0.204 atoms[/tex]
