Question

The trajectory of a projectile is represented by $y=\sqrt{3x}-{gx}^2/2$. The angle of projection is

• A. ${30}^0$
• B. ${45}^0$
• C. ${60}^0$
• D. None of these

Answer 1

The correct option is C ${60}^0$

Given equation

$y=\sqrt{3x}-\frac{g{x}^2}{2}$

equation of trajectory

$y=tan\theta x-\frac{1}{2}\frac{g{x}^2}{u^{2}co{s}^2\theta }$

compare both equation

$tan\theta =\sqrt{3}$

so $\theta ={60}^{\circ }$
