The locus of the centre of a circle which cuts a given circle orthogonally and also touches a given straight line is (a) circle (c) parabola (b) line (d) ellipse

Find the locus of the centres of the circle which cut the circles x^(2)+y^(2)+4x-6y+9=0 and x^(2)+y^(2)+4x+6y+4=0 orthogonally

Find the locus of centres of circles which touch two intersecting lines.

The circles having radii 1,2,3, touch each other externally then find the radius of the circle which cuts the three circles orthogonally

The locus of the centre of the circle which cuts the circle x^(2)+y^(2)-20x+4=0 orthogonally and touches the line x=2 is

The radical center of three given circles will be the center of a fourth circle which cuts all the three circles orthogonally.

Two circles are given such that they neither intersect nor touch.Then identify the locus of the center of variable circle which touches both the circles externally.

Find the locus of the centres of circles which touch a given line at a given point.
