The coordinates of a point on the parabola y 2 = 8x, whose focal distance is 4, are
A
B
(1, ± ± 2 √ √ 2)
C
(2, ± ± 4)
D
None
Text Solution
Verified by ExpertsThe correct answer is:
C
If the coordinates of a point on the parabola y 2 = 4ax are P(x,
y), then its focal distance is SP = x + a.
Here a = 2 and SP = 4.
4 = x +2 ⇒ ⇒ x = 2 ⇒ ⇒ y 2 = 8x2 ⇒ ⇒ y = ± ± 4.
Hence is the correct answer.
