Question:
Locus of the feet of the perpendiculars drawn from vertex of the parabola <span class="math-inline">\(y^2=4ax\)</span> upon all such chords of the parabola which subtend a right angle at the vertex is
x^2 + y^2 - 4ax = 0
x^2 + y^2 - 2ax = 0
x^2 + y^2 + 2ax = 0
x^2 + y^2 + 4ax = 0
Step-by-Step Solution
Key Concept: General
\frac{x^{2}}{4} + \frac{y^{2}}{8} = 1
Correct Answer: 1
