A) \[\mathbf{i}+2\mathbf{j}-\mathbf{k}\]
B) \[2\mathbf{i}+\mathbf{j}-2\mathbf{k}\]
C) \[2\mathbf{i}+\mathbf{j}-\mathbf{k}\]
D) \[\mathbf{i}+\mathbf{j}-2\mathbf{k}\]
Correct Answer: B
Solution :
\[\frac{3\mathbf{i}-\mathbf{j}-3\mathbf{k}+\mathbf{i}+3\mathbf{j}-\mathbf{k}}{2}=2\mathbf{i}+\mathbf{j}-2\mathbf{k}.\]You need to login to perform this action.
