Use Stokes' theorem to find the work done by the force field F(z, y, z)- along the positively oriented curve of intersection of the cylinder 2+y 1 and the plane 3x +z 4 9.
In each of the following exercises, you are given a force field F = F(x, y), in Newtons, and a oriented, closed curve C in the xy-plane, where x and y are in meters. Use Green's Theorem to calculate the work done by F along C. 9. F(x, y) = (2,5 – yº, x3 – y5), and C is the curve which starts at (0,0), moves along a line segment to (1/V2,1/V2), moves counterclockwise along the circle of radius 1,...
