Vectors Question 209
Question: If $ \vec{a}\times \vec{b},+\vec{c}=0, $ then $ \vec{a}\times \vec{b}, $ is
Options:
A) $ \vec{a}\times \vec{b} $
B) $ \vec{c}\times \vec{b}, $
C) $ \vec{a}\times \vec{c} $
D) None of these
Correct Answer: A [a] $ \vec{a},+\vec{b},+\vec{c}=0 $ $ \ Therefore $ $ \vec{a},+\vec{c}=-\vec{b} $ $ \ Therefore $ $ (\vec{a},+\vec{c}),\times ,\vec{b},=-\vec{b},\times ,\vec{b}=0 $
or $ (\vec{a},\times ,\vec{b}),+,(\vec{c}\times ,\vec{b})=0 $
or $ \vec{a}\times ,\vec{b},=\vec{b}\times ,\vec{c} $
