Question:** An environmental scientist models soil compaction using the vector field \( \vecF(x, y) = \langle -y, x \rangle \), representing rotational stress. Find the work done by this field along the circular path \( \vecr(t) = \langle 3\cos t, 3\sin t \rangle \) for \( t \in [0, 2\pi] \). - Abu Waleed Tea
