Question

The length of conjugate axis of a hyperbola is greater than the length of transverse axis. Then the eccentricity e is,

• A. $=\sqrt{2}$
• B. $>\sqrt{2}$
• C. $<\sqrt{2}$
• D. $<\frac{1}{\sqrt{2}}$

Answer 1

Answer: (B)

$2b>2a$ or, $b>a$ or, $b/a>1$ or, $\frac{b^2}{a^2}>1$ or, $e^2−1>1\left[âˆ\mu b^2=a^2\left(e^2−1\right)or,\frac{b^2}{a^2}=e^2−1\right]$ or, $e^2>2$ or, $e>\sqrt{2}$
