H C Verma Solutions for Chapter: Physics and Mathematics, Exercise 3: OBJECTIVE II

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?

Let $\overrightarrow{C}=\overrightarrow{A}+\overrightarrow{B}$

Let the angle between two non-zero vectors $\overrightarrow{A}$ and $\overrightarrow{B}$ be $120°$ and its resultant be $\overrightarrow{C}$.

The $x$-component of the resultant of several vectors

The magnitude of the vector product of two vectors $\left|\overrightarrow{A}\right|$ and $\left|\overrightarrow{B}\right|$ may be
