If normals are drawn from a point $P(h, k)$ to the parabola $y^{2}=4 a x$, then the sum of the intercepts which the normals cut off from the axis of the parabola is (A) $(h+a)$ (B) $3(h+a)$ (C) $2(h+a)$ (D) none of these
The normals at two points $\mathrm{P}$ and $\mathrm{Q}$ on the parabola $\mathrm{y}^{2}=4 \mathrm{ax}$ meet at a point $\mathrm{R}\left(\mathrm{x}_{1}, \mathrm{y}_{1}\right)$ on the parabola then $\mathrm{PQ}^{2}$ is (a) $\left(x_{1}-8 a\right)^{2}$ (b) $\left(x_{1}-8 a\right)\left(x_{1}+4 a\right)$ (c) $\left(x_{1}-4 a\right)\left(x_{1}+8 a\right)$ (d) $x_{1}^{2}-16 a^{2}$
Normals to a parabola Show that if it is possible to draw three normals from the point $(a, 0)$ to the parabola $x=y^{2}$ shown in the accompanying diagram, then $a$ must be greater than 1$/ 2 .$ One of the normals is the $x$-axis. For what value of $a$ are the other two normals perpendicular?
