WebNov 19, 2024 · Figure 9.5.1: (a) Vector field 1, 2 has zero divergence. (b) Vector field − y, x also has zero divergence. By contrast, consider radial vector field ⇀ R(x, y) = − x, − y in Figure 9.5.2. At any given point, more fluid is flowing in than is flowing out, and therefore the “outgoingness” of the field is negative. WebAug 17, 2024 · Pretty sure the question is about $\frac{\hat{r}}{r^2}$, i.e. the electric field around a point charge. Naively the divergence is zero, but properly taking into account the singularity at the origin gives a delta-distribution. ... It is called a delta function $\delta (r)$ and has infinite height and zero width but with a finite area of $1$ at ...

WebMar 3, 2016 · Interpret a vector field as representing a fluid flow. The divergence is an operator, which takes in the vector-valued function defining this vector field, and outputs a scalar-valued function measuring the change in density of the fluid at each point. The formula for divergence is. div v ⃗ = ∇ ⋅ v ⃗ = ∂ v 1 ∂ x + ∂ v 2 ∂ y + ⋯.
