If none of the vectors

\vec{A}, \vec{B}

and

\vec{C}

are zero and if

\vec{A} \times \vec{B}=0

and

\overrightarrow{\mathrm{B}} \times \overrightarrow{\mathrm{C}}=0

, then the value of

|\vec{A} \times \vec{C}|

View answer and explanation

Correct option: B

Zero

Option B is correct. If the cross product of two vectors is zero, then the vectors are parallel or anti-parallel. Thus, all three vectors are parallel, and the cross product of A and C is zero.
