A) \[(1,2\sqrt{2})\]
B) \[(2,\sqrt{2})\]
C) \[(2,2\sqrt{2})\]
D) \[(\sqrt{2},2)\]
Correct Answer: D
Solution :
given that be = 2 and a = 2 (here a < b) \[\because \]\[{{a}^{2}}={{b}^{2}}(1-{{e}^{2}})\] \[\therefore \]\[{{b}^{2}}=8\] \[\therefore \]equation of ellipse\[\frac{{{x}^{2}}}{4}+\frac{{{y}^{2}}}{8}=1\]
