A stone projected with a speed u at an angle θ with the horizontal reaches maximum height $H_1$. When it is projected with speed u at an angle $90-\theta$ with the horizontal, it reaches maximum height $H_2$. The relation between the horizontal range R of the projectile, $H_1$ and $H_2$ is

Q.

A stone projected with a velocity u at an angle $\theta$ with the horizontal reaches maximum height $H_1$. When it is projected with velocity u at an angle $(\frac{\pi }{2}-\theta )$ with the horizontal, it reaches maximum height $H_2$.
