Let `A` and `B` be the ends of the diameters `4x-y-15=0` of the circle `x^(2)+y^(2)-6x-6y-16=0`. `A` and `B` lie on tangents at the end point on the major axis of an ellipse such that line joining `A` and `B` is a tangent to the same ellipse at a point `P`. If the equation of major axis of the ellipse is `y=x` then the distance between the foci isA. `2sqrt(2)`B. `4sqrt(2)`C. `8`D. `2sqrt(3)` |
