A) \[\overrightarrow{AB}=\overrightarrow{CD}\]
B) \[\overrightarrow{AB}\,\,\,|\,\,|\,\,\,\overrightarrow{\,CD}\]
C) \[\overrightarrow{AB}\,\,\bot \,\,\overrightarrow{CD}\]
D) None of these
Correct Answer: B
Solution :
\[\overrightarrow{AB}=-\mathbf{i}-\mathbf{j}-2\mathbf{k}\] and \[\overrightarrow{CD}=6\mathbf{i}+6\mathbf{j}+12\mathbf{k}\] Hence, \[\overrightarrow{AB}||\overrightarrow{CD}.\]You need to login to perform this action.
