17.5.21 Consider the following vector field, the circle C, and two points P and Q. F = (x,x + y) a. Without computing the divergence, does the graph suggest that the divergence is positive or negative at P and Q? b. Compute the divergence and confirm your conjecture in part (a). c. On what part of C is the flux outward? Inward? d. Is the net flux across C positive or negative? Question Help P(-1, 421) F = (x, x + y)
