$A$ projectile is thrown at an angle $\theta$ such that it is just able to cross a vertical wall of height $H$ at its highest point,as shown in the figure. The horizontal distance from the point of projection to the wall is $\sqrt{3} H$. The angle $\theta$ at which the projectile is thrown is given by:

  • A
    $\tan ^{-1}\left(\frac{1}{\sqrt{3}}\right)$
  • B
    $\tan ^{-1}(\sqrt{3})$
  • C
    $\tan ^{-1}\left(\frac{2}{\sqrt{3}}\right)$
  • D
    $\tan ^{-1}\left(\frac{\sqrt{3}}{2}\right)$
