Magnitude is distance between points
[tex]\\ \rm{:}\dashrightarrow AB=\sqrt{(2\sqrt{3}-\sqrt{3})^2+(2-1)^2}=\sqrt{3+1}=2units [/tex]
Direction is slope
[tex]\\ \rm{:}\dashrightarrow \alpha=tan^{-1}(\dfrac{2-1}{\sqrt{3}})[/tex]
[tex]\\ \rm{:}\dashrightarrow \alpha=tan^{-1}(\dfrac{1}{\sqrt{3}})[/tex]
[tex]\\ \rm{:}\dashrightarrow \alpha=\dfrac{\pi}{6}[/tex]
