A) \[\overrightarrow{PQ}\] is parallel to \[\overrightarrow{RS}\]
B) \[\overrightarrow{PQ}\] is not parallel to \[\overrightarrow{RS}\]
C) \[\overrightarrow{PQ}\] is equal to \[\overrightarrow{RS}\]
D) \[\overrightarrow{PQ}\] is parallel and equal to \[\overrightarrow{RS}\]
Correct Answer: A
Solution :
\[\overrightarrow{PQ}=3\mathbf{a}+3\sqrt{3}\mathbf{b}\] and \[\overrightarrow{RS}=2\mathbf{a}+2\sqrt{3}\mathbf{b}\] Hence \[\overrightarrow{PQ}\,||\,\overrightarrow{RS}\].You need to login to perform this action.
