Vedclass · Answer

(b)

$\vec{a}+\vec{b}+\vec{c}=\overrightarrow{0}$

$\Rightarrow \vec{a}=-\vec{b}-\vec{c}$

$\vec{a} 	imes \vec{b}=(-\vec{b}-\vec{c}) 	imes \vec{b}=-\vec{c} 	imes \vec{b}$

$\vec{b} 	imes \vec{c}=-\vec{c} 	imes \vec{b}$

$\vec{c} 	imes \vec{a}=\vec{c} 	imes(-\vec{b}-\vec{c})=-\vec{c} 	imes \vec{b}$

$	herefore \vec{a} 	imes \vec{b}=\vec{b} 	imes \vec{c}=\vec{c} 	imes \vec{a}$
