Let 
be the equation of a chord of the circle 
(in the closed half-plane 
) of diameter 10 passing through the origin. Let 
be another circle described on the given chord as its diameter. If the equation of the chord of the circle 
, which passes through the point 
and is farthest from the center of 
, is 
, then 
is equal to :
