Question

A force F=K(yi^+xj^) (where K is a positive constant) acts on a particle moving in the x-y 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 forces F on the particle is
