If $\vec{A}, \vec{B}, \vec{C}$ are non-coplanar vectors then $\frac{\vec{A} . \vec{B} \times \vec{C}}{\vec{C} \times \vec{A} . \vec{B}}+\frac{\vec{B} . \vec{A} \times \vec{C}}{\vec{C} . \vec{A} \times \vec{B}}$ is equal to

3 0 1 none of there

0

$\frac{\vec{A}  \vec{B} \vec{C}}{\vec{C} \vec{A}  \vec{B}}+\frac{\vec{B}  \vec{A} \vec{C}}{\vec{C}  \vec{A} \vec{B}}$ = 1 – 1 = 0 Hence (2) is correct answer
