Two particles are simultaneously projected in the horizontal direction from a point P at a certain height. The initial velocities of the particles are oppositely directed to each other and have magnitude v each. The separation between the particles at a time when their position vectors (drawn from the point P) are mutually perpendicular, is

$${{{v^2}} \over {2g}}$$

$${{{v^2}} \over g}$$

$${{4{v^2}} \over g}$$

$${{2{v^2}} \over g}$$
