Consider the vector field F shown in the xy-plane and looks the same in all other horizontal planes. a. At the point indicated, is the divergence. positive, negative, or zero? Give a short explanation. b. At the point indicated, determine if the curl of F is equal to the zero vector. Give a short explanation. If it is not equal to the zero vector, indicate if the curl of F would point into or out of the page. c. Is this a conservative vector field? Explain why.2 4 4 -2
