Choose the correct alternative $(s)$

If the greatest height to which a man can throw a stone is $h,$ then the greatest horizontal distance upto which he can throw the stone is $2h$.

The angle of projection for a projectile motion whose range $R$ is n times the maximum height is $\,\,tan^{-1} (4/n)$

The time of flight $T$ and the horizontal range $R$ of a projectile are connected by the equation $gT^2 = 2Rtan\theta$ where $\theta$ is the angle of projection.

All of the above
