The length of the focal chord of the parabola y 2 = 4x at a distance of 0.4 units from the origin is
Text Solution
Verified by ExpertsThe correct answer is:
D
25 units
Let, PQ is a focal chord and S is the focus
Now, OS = I
In 
OSR (R is the foot of the perpendicular from O on PQ)
Length of PQ is equal to the length of latus rectum xcosec 2 
PQ = 4(2.5) 2 = 4 x 6.25 = 25
