Let the line $\displaystyle y=\mathrm{m} x$ and the ellipse $\displaystyle 2 x^2+y^2=1$ intersect at a point P in the first quadrant. If the normal to this ellipse at P meets the co-ordinate axes at $\displaystyle \left(-\frac{1}{3 \sqrt{2}}, 0\right)$ and $\displaystyle (0, \beta)$, then $\displaystyle \beta$ is equal to :
Official answer
(1)
$\displaystyle \frac{\sqrt{2}}{3}$
