Let F$=$Cxj be the force acting on an electron in a certain region of space. Here C

is a positive constant. The electron rotates around a square in the xy$-$plane counterclockwise.

The corners of the square are $($x$,$y$)=(0,0),($LO$),($LL$).(0.$L$)$ Find the work done by the force at the end of this motion starting from the starting point and ending at the starting point. According to your findings, is this force conserved or not conserved? Explain.
