Two particles are projected simultaneously from two points, O and O' such that d is the horizontal distance and h is the vertical distance between them. They are project at the saem inclination `alpha` to the horizontal with the same speed v as shown. The time after which their separation becomes minimum is

Two particles are projected simultaneously from two points O and O' such that d is the horizontal distance and h is the vertical distance between them as show in figure. These are projected at same inclination alpha with the horizontal with the same speed v. Find an expression for time at which their separation becomes minimum.

Two particles are projected simultaneously from two points O and O' such that 10 m is the horizontal and 5 m is the vertical distance between them as shown in the figure. They are projected at the same inclination 60^@ to the horizontal with the same velocit 10 ms^(-1) . The time after which their separation becomes minimum is
