Question

can anyone explain the motion of an electron against the electric field??

Answer 1

electric field is basically the effect/influence region created by the flow of electrons(current) for a charged species
so electon is -vely charged
so wen u keep an electron near a negt\ative charged species then the electric field id gonna look something like this(sucking in=== to remember)
those are the electric field lines
so the electron is gonna get repelled and moves opposite direction of the field line
(tangential to any point u keep it on the field) away from the field lines

Answer 2

"the motion" means do you want to know what is direction of motion of electron in the field???

Answer 3

If the electron moves in the Electric field then due to negative charge on the electron it will experience electric force(F) in the opposite direction of electric field,which has been shown in the figure ...
