Question

help test reiview1)A particle subject to a force F⃗ (x,y)=<−2y,2x>moves clockwise along the arc of a circle of radius 3 centered at the origin, beginning at (0,3) and ending at (3,0). 

(a) Find the work done by F⃗ . Be sure you can explain the sign of your answer. 
Work =
(b) How much work is done if the particle moves from (0,3) to (3,0) along the circular arc as before, then in a straight line to the origin, and then in a straight line to (0,3)? Hint: Sketch this closed path and the vector field. 
Work =
