Question

A projectile is thrown from ground with a velocity of $6\widehat{i} + 8\widehat{j}$. Where $\widehat{i}$and $\widehat{j}$are respectively unit vector along horizontal direction and vertical upward direction. Then the ratio of its horizontal range and maximum height attained by it is –

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

Answer: (C)

3

Answer 2

$\frac{H}{R}$= $\frac{\tan\theta}{4}$ and tan q = $\frac{u_{y}}{u_{x}}$= $\frac{8}{6}$

\ $\frac{H}{R}$= $\frac{1}{4} \times \frac{8}{6}$= $\frac{1}{3}$
