As shown in the figure, a homogen rod with mass $\mathrm{????}=8(\mathrm{????}\mathrm{????})$ is in static equilibrium between two parallel frictional walls with a distance of $\mathrm{????}=2(\mathrm{????})$ between them. Since the coefficients of friction between the rods and walls are ${\mathrm{????}}_1=0\mathrm{.}8$ and ${\mathrm{????}}_2=0\mathrm{.}4$;

a. What is the $\frac{{\mathrm{????}}_1}{{\mathrm{????}}_2}$ ratio of the frictional forces acting on the rod?

b. Find the distance $ℎ$ in meters.
