Marks: +1, -0

A vector in

x-y

plane makes an angle of

30^{\circ}

y

-axis. The magnitude of y-component of vector is

2 \sqrt{3}

. The magnitude of

x

-component of the vector will be :

2
$\sqrt{3}$
$\frac{1}{\sqrt{3}}$
6

Solution:

A_y = A \cos 30^{\circ} = 2 \sqrt{3}

A = 4

A_x = A \sin 30^{\circ} = 2
