If in the parabola `y^2=8x` a normal chord PQ subtends right angle at the focus then its length is

If a chord which is normal to the parabola y^(2)=4ax at one end subtends a right angle at the vertex, then its slope is sqrt(k) ,then find k

If the normal chord drawn at the point t to the parabola y^(2) = 4ax subtends a right angle at the focus, then show that ,t = pmsqrt2

The normal chord of the parabola y^(2)=4ax subtends a right angle at the focus.Then the end point of the chord is

If the normal chord drawn at the point P(t) to the parabola y^(2) = 4ax subtends a right angle at the focus, then show that , = pm2
