A) \[\frac{3}{2}\mathbf{i}+\frac{3}{2}\mathbf{j}+4\mathbf{k}\]
B) \[-\frac{3}{2}\mathbf{i}+\frac{3}{2}\mathbf{j}+4\mathbf{k}\]
C) \[-\frac{3}{2}\mathbf{i}+\frac{3}{2}\mathbf{j}\]
D) None of these
Correct Answer: B
Solution :
\[{{\mathbf{b}}_{2}}=\mathbf{b}-{{\mathbf{b}}_{1}}=-\frac{3}{2}\mathbf{i}+\frac{3}{2}\mathbf{j}+4\mathbf{k}\] and obviously \[{{\mathbf{b}}_{2}}\] is perpendicular to\[\mathbf{a}.\]You need to login to perform this action.
