Electric Lines of Force (ELOF)

A negatively charged particle initially at rest is placed in an electric field that varies from point to point. There are no other fields. Then,

Two infinitely large charged planes having uniform surface charge density $+\sigma$ and $-\sigma$ are placed along $x-y$ plane and $yz$ plane, respectively as shown in the figure. Then the nature of electric lines of forces in $x-z$ plane is given by
