Detailed Solution
Download Solution PDFConcept:
Parabola, y2 = 4ax, where a > 0, then
Equation of latus rectum, x = a or x - a = 0
Calculation:
Given parabolic equation, y2 = 14x
On comparing with standard equation, y2 = 4ax, we get a = \(\frac{7}{2}\)
We know that equation of latus rectum, x - a = 0
⇒ x - \(\frac{7}{2}\) = 0
⇒ 2x - 7 = 0 .
The correct option is 4.
