Answer:
Yes
Explanation:
in a 2-D plane a vector can be resolved into its rectangular components. These are rectangular components because these are at right angles to each other. One component is directed along x-axis and is the termed as horizontal component and the other one is directed along y-axis and is termed as vertical component.
Sometimes, the vector is directed entirely along x-axis or y-axis. When the vector is along x-axis or parallel to x-axis all of its magnitude will be directed along horizontal component while its vertical component will be zero. Similarly, for a vector along y-axis, the horizontal component will be zero and the entire magnitude will be along y-axis.
Consider a vector V of magnitude 5 Newtons along x-axis. Since, V is along axis the angle made with the positive x-axis is 0.
The components of a vector are calculated as:
Horizontal component = V cos θ
Vertical component = V sin θ
θ is the angle made with positive x-axis in anti-clockwise direction which is 0 in this case.
So, the components of our vector will be:
Horizontal component = 5 cos(0) = 5
Vertical component = 5 sin(0) = 0
We have just showed, even if one of the components of a vector is 0, it still can have a non-zero magnitude.
The magnitude of a vector will be zero only when all of its components are equal to 0.
