JEE MainMathematicsEllipseMCQ+4 / −1
Let the product of the focal distances of the point (3,12)\left(\sqrt{3}, \frac{1}{2}\right)(3​,21​) on the ellipse x2a2+y2b2=1,(a>b)\frac{x^2}{a^2}+\frac{y^2}{b^2}=1,(a>b)a2x2​+b2y2​=1,(a>b), be 74\frac{7}{4}47​. Then the absolute difference of the eccentricities of two such ellipses is
  1. A
    1−223\frac{1-2 \sqrt{2}}{\sqrt{3}}3​1−22​​
  2. B
    1−32\frac{1-\sqrt{3}}{\sqrt{2}}2​1−3​​
  3. C
    3−2223\frac{3-2 \sqrt{2}}{2 \sqrt{3}}23​3−22​​
  4. D
    3−2232\frac{3-2 \sqrt{2}}{3 \sqrt{2}}32​3−22​​
