Three vectors

\vec{a}, \vec{b}

and

\vec{c}

satisfy the relation

\vec{a} \cdot \vec{b}=0

and

\vec{a} \cdot \vec{c}=0

. The vector

\vec{a}

is parallel to

View answer and explanation

Correct option: D

\vec{b} \times \vec{c}

Option D is correct because if

\vec{a} \cdot \vec{b}=0

and

\vec{a} \cdot \vec{c}=0

, then

\vec{a}

is perpendicular to both

\vec{b}

and

\vec{c}

, meaning it's parallel to their cross product.
