Let `y^2=4ax` be a parabola and `x^2+y^2+2bx=0` be a circle. If parabola and circle touch each externally then:

Let y^(2) = 4ax be a parabola and x^(2) + y^(2) + 2bx = 0 be a circle . If the parabola and the circle touch each other externally , then _

The circle x^(2)+y^(2)+2kx=0 k in R touches the parabola y^(2)=4x externally then

Length of the tangent drawn from an end of the latus rectum of the parabola y^(2)=4ax to the circle of radius a touching externally the parabola at the vertex is

Let y^(2)=4x is a parabola.Then minimum area of a circle touching parabola at (1,2) as well as x- axis is

Let A(x_(1),y_(1)) and B(x_(2),y_(2)) be two points on the parabola y^(2) = 4ax . If the circle with chord AB as a dimater touches the parabola, then |y_(1)-y_(2)| is equal to

Let A(x_(1),y_(1)) and B(x_(2),y_(2)) be two points on the parabola y^(2) = 4ax . If the circle with chord AB as a dimater touches the parabola, then |y_(1)-y_(2)| is equal to
