Question

The horizontal range is four times the maximum height attained by a projectile. The angle of projection is

$0^{\circ}$

$30^{\circ}$

$45^{\circ}$

$60^{\circ}$

Answer

$45^{\circ}$

Explanation

Solution

Given $H = 4R$ $\therefore \:\:\: \frac{u^2 \, \sin \, 2 \theta}{g} = 4 \times \frac{u^2 \, sin^2 \theta}{2g}$ or $\tan \, \theta = 1$ or $\theta = 45^\circ$
