If the chord `y = mx + c` subtends a right angle at the vertex of the parabola `y^2 = 4ax`, thenthe value of c is

If the chord y = mx +c subtends a right angle at the vertex of the parabola y^(2)=4ax then the value of c is

If a normal subtends a right angle at the vertex of a parabola y^(2)=4ax then its length is

If a normal subtends a right angle at the vertex of a parabola y^(2)=4ax then its length is

Statement 1: Normal chord drawn at the point (8, 8) of the parabola y^2=8x subtends a right angle at the vertex of the parabola. Statement 2: Every chord of the parabola y^2=4a x passing through the point (4a ,0) subtends a right angle at the vertex of the parabola.
