An ellipse, with foci at 0,2 and 0,-2  and minor axis of length 4 , passes through which of the following points?

  • A
    1, 22
  • B
    2, 2
  • Correct answer
    C
    2, 2
  • D
    2, 22

Solution

Given that be =2 and a=2
(here a<b )
∵ a2=b21-e2
∴b2=8
∴ Equation of ellipse x24+y28=1
Clearly 2, 2 lies on the ellipse.

Hence, the correct answer is option: 'C'.
