NEET Questions Solved

The range of a projectile for a given initial velocity is maximum when the angle of projection is 45°. The range will be minimum, if the angle of projection is

(1) 90°

(2) 180°

(3) 60°

(4) 75°

(1) Range $=\frac{{u}^{2}\mathrm{sin}2\theta }{g}$; when $\theta =90°$, R = 0 i.e. the body will fall at the point of projection after completing one dimensional motion under gravity.
