A vector field A that has curl. Draw a normal vector that points in the direction of V XA. e.g. when the rotation of the vector field is in the xy plane, the normal vector should point in the 2-direction. . Give your figures an appropriate title, and indicate what the objects are in your figures (e.g. electron, normal vector). ffffff T | || iff |fqfqfdfdfdfs fig fig fffffffffffffffffff1 ffff fffff | fffffff / / / / 10 | 5 6 4 2 0 2 , 4, 6 11 Plot in 3d: A vector field that has divergence, draw a red dot in the center, depicting an electron.
