|A| = magnitude of the vector [tex]\underset{A}{\rightarrow}[/tex]= 10 units

θ = angle of the vector [tex]\underset{A}{\rightarrow}[/tex] relative to positive x-axis = 30 degree

A' = component of vector [tex]\underset{A}{\rightarrow}[/tex] parallel to x-axis

Since the angle is made with the x-axis, hence the x-component of the vector [tex]\underset{A}{\rightarrow}[/tex] is given as

A' = |A| Cosθ

A' = (10) Cos30

A' = (10) (0.866)

A' = 8.66 units

There are [tex]5\sqrt{3}[/tex] units in the x-axis.

A vector represented in polar format is defined by the following form:

[tex]\vec v = (r,\theta)[/tex] (1)

Where:

  • [tex]r[/tex] - Magnitude.
  • [tex]\theta[/tex] - Direction, in sexagesimal degrees.

And the magnitude of the vector in the x-direction:

[tex]x = r\cdot \cos \theta[/tex] (2)

If we know that [tex]r = 10[/tex] and [tex]\theta = 30^{\circ}[/tex], then the magnitude of the vector in the x-direction is:

[tex]x = 10\cdot \cos 30^{\circ}[/tex]

[tex]x = 5\sqrt{3}[/tex]

There are [tex]5\sqrt{3}[/tex] units in the x-axis.
