The eccentricity of the rectangular hyperbola is Options: A . &nbsp2 B . &nbsp√2 C . &nbsp0 D . &nbspNone of these

Answer: Option B : B In case of rectangular hyperbola, a = b ⇒ b 2 = a 2 ⇒ a 2 ( e 2 − 1 ) = a 2 ⇒ e = √ 2

The eccentricity of the rectangular hyperbola is

Question

The eccentricity of the rectangular hyperbola is

Options:

A . 2

B . √2

C . 0

D . None of these

Answer: Option B
:
B
In case of rectangular hyperbola,

a = b \Rightarrow b^{2} = a^{2} \Rightarrow a^{2} (e^{2} - 1) = a^{2} \Rightarrow e = \sqrt{2}
