WebDec 17, 2024 · (l) div ( curl ( grad f )) -div (curl (Δf))-scalar field Step-by-step explanation: (a) curl f - meaningless; a curl can only be taken of a vector field (b) grad f - vector field; a gradient results in a vector field (c) div F - scalar field; a divergence results in a scalar field WebCurl. The second operation on a vector field that we examine is the curl, which measures the extent of rotation of the field about a point. Suppose that F represents the velocity field of a fluid. Then, the curl of F at point P is a vector that measures the tendency of particles near P to rotate about the axis that points in the direction of this vector. . The magnitude …
