Finding work done by force as object moves counterclockwise?

F(x,y) = (x + 2y^2) j Find the force as the object moves once counterclockwise about the circle (x-2)^2 + y^2 =1 I have no way to check my work and would appreciate it if anyone would help me. Thank you yea the j is the y component (i,j,k). in this problem there is no i or k component

1. I don't understand "F(x,y) = (x + 2y^2) j ". What is this? Is this the force? You don't say. And your "j" ~ presumably this is √(-1) . . .? It obviously isn't Joules, since that requires a capital J and force is measured in Newtons . . . . I'm really confused by your Q.; I'd like to help . . . . but can't!
