Two projectiles P1 and P2 thrown with speed in the ratio $\sqrt3$ : $\sqrt2$, attain the same height during their motion. If P2 is thrown at an angle of 60$^\circ$ with the horizontal, the angle of projection of P1 with horizontal will be :

Question

Two projectiles P₁ and P₂ thrown with speed in the ratio $\sqrt3$ : $\sqrt2$, attain the same height during their motion. If P₂ is thrown at an angle of 60$^\circ$ with the horizontal, the angle of projection of P₁ with horizontal will be :

15$^\circ$
