A physical scenario can be described by employing various sets of coordinate axes that are oriented differently. Which among the following do not depend on the orientation of these axes?
Options
- AThe component of a vector
- BA vector
- CThe value of a scalar
- DThe magnitude of a vector
Correct answer
D. The magnitude of a vector
Step-by-step solution
A vector is a physical or geometric entity that exists independently of any coordinate system. Its magnitude and direction in space remain fixed regardless of the orientation of the axes.
The value of a scalar is a single numerical value that is invariant under the rotation of coordinate axes.
The magnitude of a vector is its length, which is a scalar quantity and remains invariant regardless of the orientation of the axes.
The components of a vector are its projections along the coordinate axes. When the axes are rotated, the projections change. Hence, only the components of a vector depend on the orientation of the axes.
