Question 1

Find the work done by the force F = xyi + (y x)j over the straight line from ( 2, 1) to (2,3). E) The amount of work done is E. (Type an integer or a simplified fraction.) Find the circulation and the flux of the field F = y i - x j around and across the following curves. a. The circle r(t) = (cos t)i + (sin t)j, Ots 2x b. The ellipse r(t) = (cos t)i + (3 sin t)j, Osts 2x
