Physics Two Dimensional Motion Question 196
Question: A boat is moving with a velocity $ 3\hat{i}+4\text{ \hat{j}} $ with respect to ground. The water in the river is moving with a velocity $ -3\hat{i}-4\text{ \hat{j}} $ with respect to ground. The relative velocity of the boat with respect to water is
Options:
A) $ 8\hat{j} $ B)$ -6\hat{i}-8\hat{j} $ C) $ 6\hat{i}+8\hat{j} $ D)$ 5\sqrt{2} $
Show Answer
Answer:
Correct Answer: C
Solution:
[c] Relative velocity $ =(3\hat{i}+4\hat{j})-(-,3\hat{i}-4\hat{j})=6\hat{i}+8\hat{j}. $
