A) \[2\]
B) \[\sqrt{2}\]
C) \[4\]
D) None of these
Correct Answer: B
Solution :
Given equation of curve can be rewritten as \[\frac{{{x}^{2}}}{{{a}^{2}}}-\frac{{{y}^{2}}}{{{a}^{2}}}=1\] \[\therefore \] \[e=\sqrt{1+\frac{{{b}^{2}}}{{{a}^{2}}}}=\sqrt{1+\frac{{{a}^{2}}}{{{a}^{2}}}}\] \[\Rightarrow \] \[e=\sqrt{2}\]You need to login to perform this action.
