Short Answer

Find the work done by the force field F(x,y)=yx2+y2i+xx2+y2j\mathbf { F } ( x , y ) = - \frac { y } { x ^ { 2 } + y ^ { 2 } } \mathbf { i } + \frac { x } { x ^ { 2 } + y ^ { 2 } } \mathbf { j } on a particle that moves along the circle C: x=1+cost,y=1+sint,0t2πx = 1 + \cos t , y = 1 + \sin t , 0 \leq t \leq 2 \pi .
