Problem

A particle moves from point P(−2, 5) mP(-2,\,5)\,\text{m} to point Q(3, −1) mQ(3,\,-1)\,\text{m}. What is its displacement vector Δr\Delta \mathbf r? (a) 3 i^−1 j^ m3\,\hat{\mathbf i} - 1\,\hat{\mathbf j}\,\text{m} (b) −5 i^+6 j^ m-5\,\hat{\mathbf i} + 6\,\hat{\mathbf j}\,\text{m} (c) 5 i^−6 j^ m5\,\hat{\mathbf i} - 6\,\hat{\mathbf j}\,\text{m} (d) 5 i^+6 j^ m5\,\hat{\mathbf i} + 6\,\hat{\mathbf j}\,\text{m}
