A) \[A=\hat{i}-2\hat{j}\,;\,B=\hat{i}-5\hat{j}\]
B) \[A=\hat{i}-10\hat{j}\,;\,B=2\hat{i}-5\hat{j}\]
C) \[A=\hat{i}-5\hat{j}\,;\,B=\hat{i}-10\hat{j}\]
D) \[A=\hat{i}-5\hat{j}\,;\,B=2\hat{i}-10\hat{j}\]
Correct Answer: D
Solution :
The pair of vectors are parallel \[A=\hat{i}-5\hat{j}\] and\[B=2\hat{i}-10\hat{j}\].Because B = 2A
