WebThe divergence can also be deﬁned in two dimensions, but it is not fundamental. The divergence of F~ = hP,Qi is div(P,Q) = ∇ ·F~ = P x +Q y. In two dimensions, the divergence is just the curl of a −90 degrees rotated ﬁeld G~ = hQ,−Pi because div(G~) = Q x − P y = curl(F~). The divergence measures the ”expansion” of a ﬁeld. If a WebMar 24, 2024 · The curl of a vector field, denoted curl(F) or del xF (the notation used in this work), is defined as the vector field having magnitude equal to the maximum "circulation" at each point and to be oriented perpendicularly to this plane of circulation for each point. More precisely, the magnitude of del xF is the limiting value of circulation per unit area. Written …

Web1st step. All steps. Final answer. Step 1/1. To check if a vector field is an electrostatic field, we can apply two tests: the curl test and the divergence test. The curl test involves taking the curl of the vector field, which gives another vector field. For an electrostatic field, the curl should be zero everywhere in the domain of the field.
