A force F = –K(yi + xj) (where K is a positive constant) acts on a particle moving in the xy–plane. Starting from the origin, the particle is taken along the positive x–axis to the point (a, 0) and then parallel to the y–axis to the point (a, a). The total work done by the force F on the particles is:
