The divergence of vector point function is scalar quantity and curl of vector point function is vector quantity.Answer and Explanation: Given A vector field {eq}F\left( {x,y,z} \right) = \left( { - 6yz, - 9xz,xy} \right) {/eq}. The vector point function...
of a vector field A, the vector characteristic of a “rotating component” of field A. The curl is represented by the symbol rot A. It can be interpreted in the following manner: Let A be the velocity field of a fluid flow. At a given point of the flow we place a small wheel with...
The divergence of a vector field is a scalar function. Divergence measures the “outflowing-ness” of a vector field. If vv is the velocity field of a fluid, then the divergence of vv at a point is the outflow of the fluid less the inflow at the point. The curl of a vector field...
