A) 2 i
B) 2 j
C) 2 j
D) 2 i
Correct Answer: A
Solution :
Since position vector of a point \[C\] with respect to \[B\] is \[\overrightarrow{BC}=\mathbf{i}+\mathbf{j}\] ?..(i) Similarly, \[\overrightarrow{AB}=\mathbf{i}-\mathbf{j}\] ?..(ii) Now by (i) and (ii), \[\overrightarrow{AC}=\overrightarrow{AB}+\overrightarrow{BC}=2\mathbf{i}.\]You need to login to perform this action.
