1.	If a variable line has its intercepts on the co-ordinate axes e,e′, where e2, e′2 are the eccentricities of a hyperbola and its conjugate hyperbola, then the line always touches the circle x2+y2=r2, where r=
Answer» If a variable line has its intercepts on the co-ordinate axes $e, e^{'}$ , where $\frac{e}{2}, \frac{e^{'}}{2}$ are the eccentricities of a hyperbola and its conjugate hyperbola, then the line always touches the circle $x^{2} + y^{2} = r^{2}$ , where $r =$
