Question

Let the length of the latus rectum of an ellipse with its major axis long x – axis and center at the origin, be 8. If the distance between the foci of this ellipse is equal to the length of the length of its minor axis, then which one of the following points lies on it?
(A) (4, √2, 2√2) (B) (4√3, 2√2)
(C) (4, √3, 2√3) (D) (4√2, 2√3)

Answer 1

Answer:Option B is the answer. Was single correct question. All other options have been checked, refer solution. (Image attached)

Step-by-step explanation:

Just follow as the question says.

Used formulas 1. Length of lagta rectum= 2b^2/a

2.distance between focii=2ae

3.b^2=a^2(1-e^2)
