Two particles \( P \) and \( Q \) are projected simultaneously away from each other from a point \( A \) as shown in figure. The velocity of \( P \) relative to \( Q \) in \( \mathrm{ms}^{-1} \) at the instant when the motion of \( P \) is horizontal is
(1) \( 10 \sqrt{4-\sqrt{3}} \)
(2) \( 20 \sqrt{4-\sqrt{3}} \)
(3) \( 10 \sqrt{4+\sqrt{3}} \)
(4) \( 20 \sqrt{4+\sqrt{3}} \)
