The locus of the centre of a circle, which touches externally the circle x2 + y2 - 6x - 6y + 14 = 0 and also touches the y-axis, is given by the equation

(a) x2 - 6x - 10y + 14 = 0

(b) x2 -10x - 6y + 14 = 0

(c) y2 - 6 x - 10y + 14 = 0

(d) y2 - 10x - 6y + 14 = 0                                                                  

Solution: (d)

We have x2 + y2 - 6x - 6y + 14 = 0

Let C be the centre of the circle. So, the coordinates of the centre of the circle is C (3, 2). 

 Since CA and CB are perpendicular to PA and PB, CP is the diameter of the circumcircle of triangle PAB.

So, the equation of the circle with the end points of the diameter as (1, 8) and (3, 2) is
