Question

The maximum horizontal range of a projectile is 400 m. The maximum value of height attained by it will be

• A. 100 m
• B. 200 m
• C. 400 m
• D. 800 m

Answer 1

The correct option is B

200 m

$R_{max}=\frac{u^2}{g}=400m$ $(For\theta ={45}^{\circ })$
$H_{max}=\frac{u^2}{2g}=\frac{400}{2}=200m$ $(For\theta ={90}^{\circ })$
