[6.5] - Divergence / Curl : Visual

At the point indicated in each graph, estimate both the divergence (negative, postive, or zero) and the curl ( $\hat{k}$ component: negative, positive, or 0).

top left: $\vec{\nabla} \cdot \vec{F} = 0; \vec{\nabla} \times \vec{F} = 0$ top right: $\vec{\nabla} \cdot \vec{F} > 0; \vec{\nabla} \times \vec{F} = 0$

bottom left: $\vec{\nabla} \cdot \vec{F} < 0; \vec{\nabla} \times \vec{F} = 0$
bottom right: $\vec{\nabla} \cdot \vec{F} = 0; \vec{\nabla} \times \vec{F} = [negative number] \hat{k}$
