The following pictures each show a vector field F = F1(x, y)i + F2(x, y)j + 0k in the xy-plane. Some of the vector fields pictured have curl equal to zero everywhere, V X F = 0. Identify them. - This vector field does not have curl equal to zero (which pictures)? - This vector field has curl equal to zero (which pictures)?10 -10 -5 10 A 10 -5 5 10 B 10 -5 10 -10 -5 10 C10 -10 -10 -5 5 10 D 10 10 -10 -5 10 E
