A circle touches the x-axis and also thouches the circle with center (0, 3) and radius 2. The locus of the center of the circle is a circle                    (b)  an ellipse a parabola               (d)  a hyperbola

A circle touches the x -axis and also touches the circle with center (0,3) and radius 2. The locus of the center

A circle C touches the x-axis and the circle x ^(2) + (y-1) ^(2) =1 externally, then locus of the centre of the circle C is given by

A circle with centre (h,k) .If the circle touches x -axis then the radius of the circle is

The line y=x is a tangent at (0,0) to a circle of radius unity.The center of the circle is

If one end of the diameter of a circle is (3, 4) which touches the x-axis then the locus of other end of the diameter of the circle is

If one of the diameters of the circle x^(2)+y^(2)-2x-6y+6=0 is a chord to the circle with center (2,1) ,then the radius of the circle is

A circle touches the parabola y^(2)=4x at (1,2) and also touches its directrix.The y- coordinates of the point of contact of the circle and the directrix is-

A circle touches the line L and the circle C_(1) externally such that both the circles are on the same side of the line,then the locus of centre of the circle is (a) Ellipse (b) Hyperbola (c) Parabola (d) Parts of straight line
