- Let F = -9zi+ (xe"z – 2xe*)}+ 12 k. Find f, F•JÃ, and let S be the portion of the plane 2x + 3z = 6 that lies in the first octant such that 0 < y< 4 (see figure to the right), oriented upward. Can Stokes' Theorem be used to find the flux of F through S? Clearly answer yes or no, and then briefly explain your answer.arrow_forwardUse Green's Theorem to find the counterclockwise circulation of F around the closed curve C. F=(x²+y²)i+(x-y)j; C is the rectangle with vertices at (0,0), (2,0), (2,2), (0,2)arrow_forward(a) Find the work done by the force ♬ = yî + xj + z in moving from (−1, 2, 5) to (1, 0, 1) on C, the curve of intersection of the paraboloid z = x² + y² and the plane x + y = 1.

Use Green's theorem to find the flux and circulation for the vector field: f(x, y) = (2x+ y)i+(x² +y)j across and around the boundary of the closed curve defined by: The line x 0 (0arrow_forwardLet F(x,y,z) = (-xy, x, 0) and let C be the curve of intersection of the plane x+y+z=1 and the cylinder x² + y² = 1, oriented counterclockwise when viewed from above. (a) Sketch the surfaces and highlight the curve of intersection C. (b) Parametrize the curve C. (c) Evaluate f. F. dr using the definition; that is f F · dr = ſ'° F (F(t)) · F¹' (t)dt. (d) Compute the curl of F. (e) Use Stokes' theorem to compute fF.dr. You should get the same result as in (c).arrow_forwardLet F =. Compute the flux of curl(F) through the surface z = 1- x² - y² for x² + y² ≤ 11 oriented with an upward-pointing normal. Flux = help (fractions) (Use symbolic notation and fractions where needed.) Hint: Stokes' Theorem shows a direct computation can be done in an alternative fashion.arrow_forwardExercise: 5 a) Find the outward flux of the vector field F(x, y, z) = x³i + y³j+ (z³ + xz)k across the surface of the region that is enclosed by the hemisphere z = a² – x² – y2 and the plane z = 0. b) Use the transformation u = 2x – y, v = x + 3y to find JJ, (2х-у)3 dA, where R is the rectangular region enclosed by the lines 2x – y = 0, 2x – y = 1, x + 3y = 1, x + 3y = 3.arrow_forwardUse Stokes' Theorem to find the work done on a particle moves along the line segments from the origin to the points (2,0,0) (2,4,3) , (0,4,3). and back to the origin. Note that this (counterclockwise) path is a rectangle on the plane z = 3/4 y. The motion is under the influence of the force field F = z2 i+ 2xy j + 4y2 karrow_forwardarrow_back_iosarrow_forward_ios
