Two particles are projected from the same point with the same speed, at different angles `theta_1` and` theta_2` to the horizontal. Their times of flight are `t_1` and `t_2`respectively and they have the same horizontal range. Then the incorrect relation is

A

`t_1/t_2=tan theta_1`

B

`theta_1+theta=90^@`

C

`t_1/sin theta_1 =t_2/sin theta_2`

D

`t_1/t_2 = tan theta_2`

Two stones are projected with the same speed but making different angles with the horizontal. Their ranges are equal. If the angle of projection of one is (pi^c)/3 and its maximum height is H, then the maximum height of the other is

A particle of mass m is projected from the ground with an initial speed u_0 at an angle alpha with the horizontal. At the highest point of its trajectory, it makes a completely inelastic collision with another identical particle, which was thrown vertically upward from the ground with the same initial speed u_0. The angle that the composite system makes with the horizontal immediately after the collision is
