Physics - W.E.P. Question with Solution | TestHub

A force$\overrightarrow{F}=-K\left(y\widehat{\text{i}}+x\widehat{\text{j}}\right)$(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$(a,a)$. The total work done by the force$\overrightarrow{F}$on the particle is
