Physics · MOTION IN A PLANE
हिन्दीA person moves with a velocity of \( 3\text{ m/s} \) due East, while wind is blowing with a velocity of \( 4\text{ m/s} \) due North. The magnitude of the velocity of the wind relative to the person is:
Correct answer · Option 2
\( 5\text{ m/s} \)
Explanation
Relative velocity \( \mathbf{v}_{rel} = \mathbf{v}_w - \mathbf{v}_p = 4\hat{j} - 3\hat{i} \). Magnitude \( |\mathbf{v}_{rel}| = \sqrt{(-3)^2 + 4^2} = 5\text{ m/s} \).
