Q1. Evaluate the line integral f (x2 + y2)dx + 2xydy by two methods a) directly, b) using Green's Theorem, where C consists of the arc of the parabola y = x2 from (0,0) to (2,4) and the line segments from (2,4) to (0,4) and from (0,4) to (0,0). [Answer: 0] Q2. Use Green's Theorem to evaluate the line integral $. F. dr or the work done by the force field F(x, y) = (3y - 4x)i +(4x - y)j...
1. Suppose F = (-y,x,z) and S is the part of the sphere x2 + y2 + z = 25 below the plane z = 4, oriented with the outward-pointing normal (so that the normal at (5,0,0) is 1). Compute the flux integral curl F.ds using Stoke's theorem.
6. Let S be the part of the cylinder x2 + y2 = 4 that lies between the two planes z = 2 – X and z = –2 – x. Note that S meets either plane on an ellipse, equipped with the outward normal of the cylinder. Sketch S and find the flux of the vector field F = (2x, y, x) through S.
(7) Let V be the region in R3 enclosed by the surfaces+2 20 and z1. Let S denote the closed surface of V and let n denote the outward unit normal. Calculate the flux of the vector field F(x, y, z) = yi + (r2-zjy + ~2k out of V and verify Gauss Divergence Theorem holds for this case. That is, calculate the flux directly as a surface integral and show it gives the same answer as the triple integral...
