The centers of the circles touching both the coordinate axes lies on the line
x – y = 0 or x + y = 0 according to the quadrant in which the circle lies.
Based on this data answer the following 2 questions.
A) If the difference between the radii of the circles passing through (a, b) and touching the axes is C > 0 and a, b > 0 then the least value of a + b is
B) If one of the points of intersection of the two circles touching the axes is (p,q) then the length of the common chord is
