A parabola is drawn through two given points `A(1,0)` and `B(-1,0)` such that its directrix always touches the circle `x² + y^2 = 4.` Then, The locus of focus of the parabola is=A. `(x^(2))/(4) +(y^(2))/(3) = 1`B. `(x^(2))/(4) +(y^(2))/(5) =1`C. `(x^(2))/(3)+(y^(2))/(4) = 1`D. `(x^(2))/(5)+(y^(2))/(4)=1` |
