The sum of the squares of the perpendicular on any
\( \mathrm{P}^{15} \) tangent to the ellipse \( \frac{x^{2}}{a^{2}}+\frac{y^{2}}{b^{2}}=1 \) from two points

W
on the minor axis, each at a distance \( \sqrt{a^{2}-b^{2}} \) from the centre, is
(1) \( 2 a^{2} \)
(2) \( 2 b^{2} \)
(3) \( \dot{a}^{2}+b^{2} \)
(4) \( a^{2}-b^{2} \)
