MCQ
The eccentricity of the hyperbola $2{x^2} - {y^2} = 6$ is
  • A
    $\sqrt 2 $
  • B
    $2$
  • C
    $3$
  • $\sqrt 3 $

Answer

Correct option: D.
$\sqrt 3 $
d
(d) $\frac{{{x^2}}}{{(6/2)}} - \frac{{{y^2}}}{6} = 1$

==> ${a^2} = 3$ and ${b^2} = 6$

Therefore $e = \sqrt {\frac{{{b^2}}}{{{a^2}}} + 1} $

==> $e = \sqrt 3 $.
