A force F=−k(yi+xj) acts on a particle | Fountain Physics | Work Power Energy | NEET | JEE | Boards

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). Find the total work done by the force F on the particle
