The force field 1. work done = 3 units F(x, y) = 3yi+ (x3 + 3xy?) j O 2. work done = 6 units moves a particle along the path C that starts at (-2, 0), goes along the r-axis to (2, 0), and X 3. work done = 127 units then around the semicircle 4. work done = 37 units y = V4-x2 5. work done = 67 units back to (-2, 0) as shown in 6. work done = 12 units Use Green's Theorem to determine the work done in moving the particle along C
