Find the work done by F over the curve in the direction of increasing t. F = 3xyi + yj - yzk r(t) = ti + t j + tk, Osts 1 Work = (Type an integer or a simplified fraction.)Find the work done by F in moving a particle once counterclockwise around the given curve. F = (2x - 5y)i + (5x - 2y)j C: The circle (x - 1)2 + (y - 1)2 = 1 . . . What is the work done in one counterclockwise circulation? (Type an exact, using it as needed.)
