Question

$[\overrightarrow{a}\overrightarrow{b}\overrightarrow{c}]$ is the scalar product of three vectors $\overrightarrow{a},\overrightarrow{b}$ and $,\overrightarrow{c}$ . Then $[\overrightarrow{a}\overrightarrow{b}\overrightarrow{c}]$ is equal to

• A. $[\overrightarrow{b}\overrightarrow{a}\overrightarrow{c}]$
• B. $[\overrightarrow{c}\overrightarrow{b}\overrightarrow{a}]$
• C. $[\overrightarrow{b}\overrightarrow{c}\overrightarrow{a}]$
• D. $[\overrightarrow{a}\overrightarrow{c}\overrightarrow{b}]$

Answer 1

Answer: (C)

$\left[\vec{a}\vec{b}\vec{c}\right]=\left[\vec{b}\vec{c}\vec{a}\right]$ ($\because$ cyclic order remain the same)
