Problem

Let O(0,0),A(12,0),O(0,0), A(\tfrac{1}{2}, 0), and B(0,32)B(0, \tfrac{\sqrt{3}}{2}) be points in the coordinate plane. Let F\mathcal{F} be the family of segments PQ¯\overline{PQ} of unit length lying in the first quadrant with PP on the xx-axis and QQ on the yy-axis. There is a unique point CC on AB¯\overline{AB}, distinct from AA and BB, that does not belong to any segment from F\mathcal{F} other than AB¯\overline{AB}. Then OC2=pqOC^2 = \tfrac{p}{q}, where pp and qq are relatively prime positive integers. Find p+qp + q.
Plain-text mathematical notation (without MathML)
Let O(0,0),A((1)/(2),0), and B(0,(√(3))/(2)) be points in the coordinate plane. Let F be the family of segments (PQ)¯ of unit length lying in the first quadrant with P on the x-axis and Q on the y-axis. There is a unique point C on (AB)¯, distinct from A and B, that does not belong to any segment from F other than (AB)¯. Then OC²=(p)/(q), where p and q are relatively prime positive integers. Find p+q.
Original LaTeX notation
Let $O(0,0), A(\tfrac{1}{2}, 0),$ and $B(0, \tfrac{\sqrt{3}}{2})$ be points in the coordinate plane. Let $\mathcal{F}$ be the family of segments $\overline{PQ}$ of unit length lying in the first quadrant with $P$ on the $x$-axis and $Q$ on the $y$-axis. There is a unique point $C$ on $\overline{AB}$, distinct from $A$ and $B$, that does not belong to any segment from $\mathcal{F}$ other than $\overline{AB}$. Then $OC^2 = \tfrac{p}{q}$, where $p$ and $q$ are relatively prime positive integers. Find $p + q$.
