If \(\bar{a}, \bar{b}, \bar{c}\) are the non-coplanar vectors and \(\bar{a}-2 \bar{b}+3 \bar{c}\), \(-4 \bar{a}+5 \bar{b}-6 \bar{c}, x \bar{a}-9 \bar{b}+z \bar{c}\) are collinear points then \(2 x-z=\)
- A -10
- B -9
- C 0
- D 9
Answer & Solution
Correct Answer
(C) 0
Step-by-step Solution
Detailed explanation
Let points \(\mathrm{A}_{-}^{\mathrm{A}}:(\overline{\mathrm{a}}-2 \overline{\mathrm{b}}+3 \overline{\mathrm{c}}), \mathrm{B}:(-4 \overline{\mathrm{a}}+5 \overline{\mathrm{b}}-6 \overline{\mathrm{c}})\) and \(C:(x \bar{a}-9 \bar{b}+z \bar{c})\) Since, points…
