Question

An object is projected so that its horizontal range $R$ is maximum. If the maximum height attained by the object is $H$, then the ratio of $R/H$ is

• A. $4 : 1$
• B. $1 : 4$
• C. $2 : 1$
• D. $1 : 2$

Answer 1

Answer: (A)

$4 : 1$

Answer 2

$R=4 H \cot \theta$ Here, $\theta=45^{\circ}$
then $R=4 H$
$\Rightarrow \frac{R}{H}=\frac{4}{1}$
