Question

The latus rectum of an ellipse is 10 and the minor axis is equal to the distance between the foci. The equation of the ellipse is

• A.
• B.
• C.
• D. None of these

Answer 1

The correct option is A

Given $\frac{2b^2}{a}=10$ and 2b = 2ae

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