A projectile can have the same range for two angles of projection. If $h_1$ and $h_2$ are maximum heights when the range in the two cases is $R$, then the relation between $R$, $h_1$ and $h_2$ is

  • [AIIMS 2013]
  • A
    $R = 4\sqrt {{h_1}{h_2}} $
  • B
    $R = 2\sqrt {{h_1}{h_2}} $
  • C
    $R = \sqrt {{h_1}{h_2}} $
  • D
    None of these
