The range of a projectile for a given initial velocity is maximum when the angle of projection is ${45^o}$. The range will be minimum, if the angle of projection is ......... $^o$
$90$

The range of a projectile for a given initial velocity is maximum when the angle of projection is ${45^o}$. The range will be minimum, if the angle of projection is ......... $^o$
Range$ = \frac{{{u^2}\sin 2\theta }}{g}$; when $\theta = 90^\circ $, $R = 0$ i.e. the body will fall at the point of projection after completing one dimensional motion under gravity.
