Question

In the hyperbola the distance between the foci is equal to distance between one focus to one end of conjugate axis then its eccentricity

• A. $\frac{5}{2}$
• B. $\frac{7}{2}$
• C. $\frac{7}{3}$
• D. does not exist

Answer 1

The correct option is D does not exist

Given $2ae=a(1+e)$
$\therefore$ distance betwwen foci and conjugate axis is $ae+a$
$\Rightarrow ae=a$
$e=1$
$\therefore$ its not a hyperbola ,so eccentricity does not exist
