Question

A situation may be described by using different sets of coordinate axes having different orientations. Which of the following do not depend on the orientation of the axes ?
(a) the value of a scalar

(b) component of a vector

(c) a vector

(d) the magnitude of a vector.

Answer 1

(a) the value of a scalar

(c) a vector

(d) the magnitude of a vector.

Explanation:

The value of a scalar, a vector and the magnitude of a vector do not depend on a given set of coordinate axes with different orientation. However, components of a vector depend on the orientation of the axes.
