A) \[5\overrightarrow{OC}\]
B) \[\frac{1}{3}\,(2\mathbf{i}-2\mathbf{j}+\mathbf{k})\]
C) \[\,\overrightarrow{OC}\]
D) None of these
Correct Answer: A
Solution :
\[2\overrightarrow{OA}+3\overrightarrow{OB}=2(\overrightarrow{OC}+\overrightarrow{CA})+3\,(\overrightarrow{OC}+\overrightarrow{CB})\] \[=5\overrightarrow{OC}+2\overrightarrow{CA}+3\overrightarrow{CB}=5\overrightarrow{OC}\], \[\{\because \,2\overrightarrow{CA}=-3\overrightarrow{CB}\}\].You need to login to perform this action.
