NEET Physics QUESTION #7333

Question 1

A particle starts from the origin (0, 0) and moves in a straight line. At a later time its position is $(\sqrt{3},\,3)$. The angle the path makes with the positive $x$-axis is:

$0°$
$30°$
$45°$
$60°$✔️

Correct Answer Explanation

$\tan\alpha = \dfrac{y}{x} = \dfrac{3}{\sqrt{3}} = \sqrt{3}$

$\alpha = \tan^{-1}(\sqrt{3}) = \mathbf{60°}$
