Two projectiles are thrown with the same initial velocity making angles of $45^\circ$ and $30^\circ$ with the horizontal respectively. The ratio of their respective ranges will be
Answer: (C) $2 : \sqrt3$
$R\propto\sin2\theta$: $\dfrac{R_1}{R_2} = \dfrac{\sin90^\circ}{\sin60^\circ} = \dfrac{1}{\sqrt3/2} = \dfrac{2}{\sqrt3}$.
