v =

e^²

/ ( 4* π

v =

e^²

/ ( 4* π

* ε0* n* ℏ)

$v$ = $\frac{e^{2}}{4\cdot \pi\cdot \varepsilon0\cdot n\cdot \hbar}$

v =

e^²

/ 4/ n/ ε0/ π

/ ℏ

$v$ = $\frac{e^{2}}{4\cdot n\cdot \varepsilon0\cdot \pi\cdot \hbar}$

v =

0.25* e^²

/ n/ ε0/ π

/ ℏ

$v$ = $\frac{0.25\cdot e^{2}}{n\cdot \varepsilon0\cdot \pi\cdot \hbar}$
