Physics · MOTION IN A PLANE
हिन्दीIn the position and displacement graph shown, if point P has coordinates \( (2, 1)\text{ m} \) and point P' has coordinates \( (6, 4)\text{ m} \), what is the magnitude of the displacement vector \( \mathbf{PP'} \)?
Correct answer · Option C
\( 5\text{ m} \)
Explanation
\( \mathbf{PP'} = (6-2)\hat{i} + (4-1)\hat{j} = 4\hat{i} + 3\hat{j}\text{ m} \). Its magnitude is \( |\mathbf{PP'}| = \sqrt{4^2 + 3^2} = 5\text{ m} \).
