Question

Topic: Circles & Straight Lines
Three circles touch one another externally the tangents at their points of contact meet
at a point whose distance from point of contact is 4. The ratio of the product of the
radii to the sum of the radii of the circles is
1 1
2 16
32
48
Two chords which are drawn from a point (a,b) on the circles x(x - a) + y(y-b)= 0)
are bisected by x -axis then
1) a² < 86² 2 a² = 86² 3) a² > 86² 4) 3a² > 4b²
An equation of the chord of the circle x² + y2 = a' passing through (2,3) farthest from
the centre of the circle (given that a > 113 ) is
1) 2x + 3y=13 2) 3x +2y=133) 2x + 3y=-1 4) 3x +2y=-1
Two circles are such that each of them pass through (1,2) and touch both the lines
X+ y +2=0) and 7x + y +1=0 then the area of triangle formed by their common
chord with co-ordinates axes is​
