## Question

### Solution

Correct option is Equation of the line parallel to the axis and bisecting the ordinate PN of the point P(at2, 2at) is y = at which meet the parabola

y2 = 4ax at the point .

Coordinates of N are (at2, 0).

Equation of QN is Which meets the tangent at the vertex, = 0, at the point  #### SIMILAR QUESTIONS
