If \(\bar{a}=\hat{i}+\hat{j}+\hat{k}, \bar{b}=4 \hat{i}+3 \hat{j}+4 \hat{k}\) and \(\bar{c}=\hat{i}+\alpha \hat{j}+\beta \hat{k}\) are linearly dependent vectors and \(|\overline{\mathrm{c}}|=\sqrt{3}\), then the values of \(\alpha\) and \(\beta\) are respectively.
- A 1,1
- B 2,1
- C 0,1
- D 1,2
Answer & Solution
Correct Answer
(A) 1,1
Step-by-step Solution
Detailed explanation
Note that only for option (A), i.e., for \(\alpha=1\) and \(\beta=1,|\vec{c}|=\sqrt{3}\) holds true.
\(\therefore \quad\) Option (A) is correct.
\(\therefore \quad\) Option (A) is correct.
