Question 1 of 5

$\mathrm{C}_{1}$ is a fixed circle and $\mathrm{C}_{2}$ is the director circle of $\mathrm{C}_{1}$ . A third circle $\mathrm{C}_{3}$ passes through the centre of $\mathrm{C}_{1}$ and intersects $\mathrm{C}_{2}$ at $\mathrm{P}$ and $\mathrm{Q}$ and $\mathrm{C}_{1}$ at A and B such that the line PQ is a tangent to $\mathrm{C}_{1}$ . Find $\frac{\mathrm{AB}}{\mathrm{PQ}}$ .
