Vectors Question 179
Question: A boat is moving with a velocity $ 3\hat{i}+4\hat{j} $ with respect to ground. The water in the river is moving with a velocity $ 3\hat{i}4\hat{j} $ with respect to ground. The relative velocity of the boat with respect to water is
[CPMT 1998]
Options:
A) $ 8\hat{j} $
B) $ 6\hat{i}8\hat{j} $
C) $ 6\hat{i}+8\hat{j} $
D) $ 5\sqrt{2} $
Correct Answer: C Relative velocity $ =( 3\hat{i}+4\hat{j} )( 3\hat{i}4\hat{j} )
