JEE Math Practice Question
Consider the parabola with vertex $$\left( {{1 \over 2},{3 \over 4}} \right)$$ and the directrix $$y = {1 \over 2}$$. Let P be the point where the parabola meets the line $$x = - {1 \over 2}$$. If the normal to the parabola at P intersects the parabola again at the point Q, then (PQ)2 is equal to :
- A.$${{75} \over 8}$$
- B.$${{125} \over {16}}$$
- C.$${{25} \over 2}$$
- D.$${{15} \over 2}$$
