The normal at a point `P(theta)` on the ellipse `5x^2 +14y^2=70` cuts the curve again at a point `Q(2theta)` then `costheta`θ

The normal at a point P(theta) on the ellipse 5x^(2)+14y^(2)=70 cuts the curve again at a point Q(2 theta) then cos thetahat I

If the normal at the point P(theta) to the ellipse (x^(2))/(14)+(y^(2))/(5)=1 intersects it again at the point Q(2 theta), then cos theta is equal to (A)(2)/(3)(B)(-2)/(3) (C) (3)/(4) (D) non of these

If the normal at the point P( theta) to the ellipse (x^(2))/(14)+(y^(2))/(5)=1 intersects it again at the point Q (2 , theta) then cos theta is equal to
