Solution

Locus of Point on Parabola

Given: Point on parabola $y^2 = 4a x$ is at distance $5a$ from focus $(a, 0)$ .

Distance Equation:

$(x - a)^2 + y^2 = 25a^2 \Rightarrow (x - a)^2 + 4a x = 25a^2 \Rightarrow x^2 + 2a x - 24a^2 = 0$

Solving gives: $x = 4a$ , $y = 4a$

✅ Final Answer: $\boxed{(4a,\ 4a)}$

Solution

Locus of Midpoint of Chords

Given Parabola: $y^2 = 4x$

Condition: Chords pass through the vertex $(0, 0)$

Let the other end of the chord be $(x_1, y_1)$ , so the midpoint is:

$M = \left( \frac{x_1}{2}, \frac{y_1}{2} \right) = (h, k)$

Since the point lies on the parabola: $y_1^2 = 4x_1$

⇒ $(2k)^2 = 4(2h)$

⇒ $4k^2 = 8h$

⇒ $\boxed{k^2 = 2h}$

✅ Locus of midpoints: $y^2 = 2x$
