Let ABCD be a square of side length 2 units. $\mathrm{C}_2$ is the circle through vertices $\mathrm{A}, \mathrm{B}, \mathrm{C}, \mathrm{D}$ and $\mathrm{C}_1$ is the circle touching all the sides of the square $\mathrm{ABCD} . \mathrm{L}$ is a line through A .
If P is a point on $\mathrm{C}_1$ and Q in another point on $\mathrm{C}_2$, then $\frac{\mathrm{PA}^2+\mathrm{PB}^2+\mathrm{PC}^2+\mathrm{PD}^2}{\mathrm{QA}^2+\mathrm{OB}^2+\mathrm{QC}^2+\mathrm{OD}^2}$ is equal to
