(1 point) Find a formula FF(x, y), F2(x, y)) for the vector field in the plane that has the properties that F(0,0) = (0,0) and that at any other point (a, b)ã¡(0.0) the vector field F is tangent to the circle x2 + y2-a2 + b and points in the counterclockwise direction with magnitude F(a, b il = 2v/a2 + b2
