Homework Statement
Calculate the first three energy leveles for an electron in a quantum well of width 10Angstrom
and infinite walls.
Homework Equations
[tex]En=\frac{n2pi2(hbar)2}{2mL2}[/tex]
The Attempt at a Solution
m=9.109E-31Kg
L=10E-10m
hbar=1.055E-34
En=n2*6.032E-20
My problem is really with the unit though.
here is what I have
[tex]\frac{Kgm2}{s}*\frac{Kgm2}{s}*\frac{1}{Kg}*\frac{1}{m2}=[/tex][tex]\frac{Kgm2}{s2}[/tex]
