Answer & Solution

Correct Answer

(C) \(\hat{i}+3 \hat{j}-5 \hat{k}\)

Step-by-step Solution

Detailed explanation

Line joining \(\hat{i}-\hat{j}+\hat{k}\) and \(\hat{i}+\hat{j}-2 \hat{k}\) is \(\vec{r}=(\hat{i}-\hat{j}+\hat{k})+\lambda(2 \hat{j}-3 \hat{k})\)...(i) Line joining \(2 \hat{i}+\hat{j}-6 \hat{k}\) and \(3 \hat{i}-\hat{j}-7 \hat{k}\) is…
