As shown in the figure below, a point charge $q$ moves from point $P$ to a point $S$ traversing a path $P Q R S$ in a uniform $\vec{E} .$ The electric field is directed along a direction parallel to $x$ -axis. The coordinates of, $P, Q, R$ and $S$ are $(a, b, 0) (2 a, 0, 0) (a, - b, 0)$ and $(0, 0, 0)$ respectively. What is the work done by the field in the process?
