Family of circles passing from points of intersection of circle and chord are
Its center is 
It lies on 
.
i.e. 
Hence equation of circle is 
.
Trick: Since 
is the line passing through origin and through 
and 
quadrant. Also centre
of the given circle lies on positive 
-axis, therefore, the centre of required circle will be in 
quadrant and must satisfy the given line 
and its equation is given by
