7. Assume (x, y,x)(2xy, y',5z - y). Let E be the solid upright cylinder between the planes z 0 and z-3 with base the disc x2 + y2 < 9, and let S be the outwardly oriented boundary surface of E. Note that S consists of three smooth surfaces; the surface Si of the cylinder, plus the top disc Di and the bottom disc D2. Follow the steps to verify the Divergence Theorem. (a) [12 pts.] Evaluate dS directly 7....
11. (20 pts) Consider the surface integral JJs F dS with F(x, y, 2) - 2xyǐ + zeij + z3k where s is the surface of the cylinder y2 + 2 = 4 with 0-x < 2. (a) Parametrize this surface and write down (but do not evaluate) the iterated integrals for the surface integral.

Please solve all parts of this question clearly and neatly 1. Let S be part of the paraboloid z = 5-22-уг, z--3. Assume that the charge density of s is (x,y,2-7x +5 -z Coulombs per unit of surface area. (a) Sketch S (b) Using a parametrisation based on cylindrical coordinates, determine a normal vector to S c) Using part (b), determine the total charge on S 1. Let S be part of the paraboloid z = 5-22-уг, z--3. Assume that...
