If P is the pole of chord AB of a parabola dnt he length of perpendiculars from A, P, B on any tangent to the curve be p_1, p_2 and p_3 , then (A) p_3 is the G.M. between P_1 and p_2 (B) p_3 is the A.M. between p_1 and p_2 (C) p_1 is the G.M. between P_1 and p_3 (D) none of these

A(x_1, y_1) and B(x_2, y_2) are any two points on the parabola y=cx^2 + bx + a . If P(x_3, y_3) be the point on the arc AB where the tangent is parallel to the chord AB , then (A) x_2 is the A.M. between x_1 and x_3 (B) x_2 is the G.M. between x_1 and x_3 (C) x_2 is the H.M. between x_1 and x_3 (D) none of these
