A) \[2\overrightarrow{AC}\]
B) \[3\overrightarrow{AB}\]
C) \[3\overrightarrow{DB}\]
D) \[2\overrightarrow{BC}\]
Correct Answer: B
Solution :
Points A, B, C, D, E are in a plane. Resultant \[=(\overrightarrow{AC}+\overrightarrow{AD}+\overrightarrow{AE})+(\overrightarrow{CB}+\overrightarrow{DB}+\overrightarrow{EB})\] \[=(\overrightarrow{AC}+\overrightarrow{CB})+(\overrightarrow{AD}+\overrightarrow{DB})+(\overrightarrow{AE}+\overrightarrow{EB})\] \[=\overrightarrow{AB}+\overrightarrow{AB}+\overrightarrow{AB}=3\overrightarrow{AB}\].You need to login to perform this action.
