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 _

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 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 parabola and circle touch each externally then:

If the circles x^(2) + y^(2) = a^(2) and x^(2) + y^(2) - 6x - 8y + 9 = 0 touches each other externally, then a = …….

If the circles x^(2) +y^(2) + ax -6y + 4 =0 and x^(2) + y^(2) - 12x + 32 =0 touch externally each other and if the distance between the centres is equal to 5, then the values of a are
