Vedclass · Answer

(B) Given vectors are $\overrightarrow A = 2\hat i + \hat j$,$\overrightarrow B = 3\hat j - \hat k$,and $\overrightarrow C = 6\hat i - 2\hat k$.We need to calculate $\overrightarrow A - 2\overrightarrow B + 3\overrightarrow C$.Substituting the given vectors:$\overrightarrow A - 2\overrightarrow B + 3\overrightarrow C = (2\hat i + \hat j) - 2(3\hat j - \hat k) + 3(6\hat i - 2\hat k)$$= 2\hat i + \hat j - 6\hat j + 2\hat k + 18\hat i - 6\hat k$Grouping the components of $\hat i$,$\hat j$,and $\hat k$:$= (2 + 18)\hat i + (1 - 6)\hat j + (2 - 6)\hat k$$= 20\hat i - 5\hat j - 4\hat k$Thus,the correct option is $B$.

If $\overrightarrow A = 2\hat i + \hat j$,$\overrightarrow B = 3\hat j - \hat k$,and $\overrightarrow C = 6\hat i - 2\hat k$,then the value of $\overrightarrow A - 2\overrightarrow B + 3\overrightarrow C$ is:
