1.	A tangent PT is drawn to the circle x2+y2=4 at the point P(√3,1). A straight line L, perpendicular to PT is a tangent to the circle (x−3)2+y2=1.A common tangent of the two circle is
Answer» A tangent $P T$ is drawn to the circle $x^{2} + y^{2} = 4$ at the point $P (\sqrt{3}, 1) .$ A straight line $L,$ perpendicular to $P T$ is a tangent to the circle $(x - 3)^{2} + y^{2} = 1.$ A common tangent of the two circle is
