" A normal is drawn to parabola "`y^(2)=4ax`" at any point "P" ,other than vertex.If it cuts the parabola again at a point "Q" .Then minimum length of "PQ" is"

If the normal to the parabola y^(2)=4ax at point t_(1) cuts the parabola again at point t_(2) .Then the minimum value of t_(2)^(2) is

If the normal to the parabola y^(2)=4ax at the point (at^(2),2at) cuts the parabola again at (aT^(2),2aT) then

The normal to the parabola y^(2)=8ax at the point (2, 4) meets the parabola again at the point

The length of the subnormal to the parabola y^(2)=4ax at any point is equal to

If the normal to the parabola y^(2)=4ax at point t_(1) cuts the parabola again at point t_(2) then prove that t_(2)^(2)>=8

IF the normal to the parabola y^2=4ax at point t_1 cuts the parabola again at point t_2 , prove that t_2^2ge8

If normal to parabola y^(2)=4ax at point P(at^(2),2at) intersects the parabola again at Q, such that sum of ordinates of the points P and Q is 3, then find the length of latus ectum in terms of t.
