PhysicsSingle correct+4 / -1Question 34 of 90

Two projectiles $P_1$ and $P_2$ thrown with speed in the ratio $\sqrt3:\sqrt2$ , attain the same height during their motion. If $P_2$ is thrown at an angle of 60° with the horizontal, the angle of projection of $P_1$ with horizontal will be :

15°

30°

45°

60°

Answer and worked solution

Official answer: C

Equal heights. $3\sin^2\theta=2\sin^260°=\frac32$ , so $\sin\theta=\frac1{\sqrt2}$ , $\theta=45°$ .

(C)
