One equation of common tangent to ellipse
\( \mathrm{P} \) \( \frac{x^{2}}{a^{2}}+\frac{y^{2}}{b^{2}}=1 \) and hyperbola \( \frac{x^{2}}{a^{2}}-\frac{y^{2}}{b^{2}}=2 \) is

W
(1) \( 2 y=\sqrt{3} b x+a b \)
(2) \( y=2 \sqrt{3} \frac{b}{a} x+2 b \)
(3) No common tangent
(4) \( a y=\sqrt{3} b x+2 a b \)
