Hint: A vector can be divided into two components along two perpendicular axes, those are called the rectangular components. Since the displacement is a vector quantity it also has the resolution along two axes. The values of the two components are cosine and sine of the angle multiplied with the magnitude of the vector. Note that, here the angle is the angle between the vector and the horizontal component.
Complete step by step answer:
In a two-dimensional coordinate system, any vector is broken into x -component and y -component. for instance, the vector \[V\] is broken into \[2\] elements, \[{V_x}\] and \[{V_y}\] . If the angle between the vector and its x -component be \[\theta \]
\[{V_x} = V\cos \theta \]
\[{V_y} = V\sin \theta \]
Here, displacement is a vector quantity. Let, the displacement vector is . given that, the angle between the vector and its x -component be \[\theta = 30^\circ \]
vector \[S\] is broken into two elements, \[{S_x}\] and \[{S_y}\].
\[{S_x} = S\cos \theta \]and \[{S_y} = S\sin \theta \]
Given, the magnitude of , \[S = 100\]
So, \[{S_x} = S\cos \theta = 100\cos 30^\circ \]
\[ \Rightarrow {S_x} = 100 \times \dfrac{{\sqrt 3 }}{2}\]
\[ \Rightarrow {S_x} = 50\sqrt 3 \]
And, \[{S_y} = S\sin \theta = {\text{100}}\sin 30^\circ \]
\[ \Rightarrow {S_y} = 100 \times \dfrac{1}{2}\]
\[ \Rightarrow {S_y} = 50\]
Hence, the horizontal and vertical components of the \[100m\] displacement will be \[ \Rightarrow {S_x} = 50\sqrt 3 \] and \[ \Rightarrow {S_y} = 50\]respectively.
Note: If we want to break the vector \[V\] along this vector itself i.e along the vector \[V\], the angle between the vector and its x -component will be \[\theta = 0^\circ \],
Such as, \[{V_x} = V\cos 0^\circ = 0\]
And, the vertical component will be \[{V_y} = V\sin 0^\circ = 0\]
From these we can conclude:
The value of the component of a vector along this particular vector will be the same as the magnitude of the vector.
There will be no vertical component of the vector in this case.
