A force F= βKπΎ(π¦iΜ+ π₯j)Μ (where πΎ is a positive constant) acts on a particle moving in the π₯ β Y plane. Starting from the origin, the particle is taken along the positive π₯-axis to the point (π, 0) and then parallel to the π¦-axis to the (π,a). The total work done by the force Fβ on the particle is
