If \(a(\alpha \times \beta)+b(\beta \times \gamma)+c(\gamma \times \alpha)=0\) and atleast one of the scalars \(a, b, c\) is non-zero, then the vectors \(\alpha, \beta, \gamma\) are
- A parallel
- B non coplanar
- C coplanar
- D mutually perpendicular
Answer & Solution
Correct Answer
(C) coplanar
Step-by-step Solution
Detailed explanation
Given that, \(a(\alpha \times \beta)+b(\beta \times \gamma)+c(\gamma \times \alpha)=0\) On taking dot product of \(\alpha\) with the given cross product, we get…
