from point `P (-1, 0)` two tangents `PQ ` and `PS ` are drawn to the parabola `y^2= 4x. Q` and `S` are lying on the parabola. Normals at point `Q`. and `S` intersect at `R,` then area of quadrilateral `PQRS` wil be

If from a point A, two tangents are drawn to parabola y^2 = 4ax are normal to parabola x^2 = 4by , then

Through a point P (-2,0), tangerts PQ and PR are drawn to the parabola y^2 = 8x. Two circles each passing through the focus of the parabola and one touching at Q and other at R are drawn. Which of the following point(s) with respect to the triangle PQR lie(s) on the radical axis of the two circles?
