Electrons enter charged capacitor

[Xuran Wu]

Homework Statement

Two electrons enter a region between charged capacitor plates with equal speed v Electron A is directed horizontally to the left while electron B is directed at 30 degrees below the horizontal. Each electron makes it to the left-hand plate. Which one of the following choices best compares the speeds of the charges(vA, vB)upon arrival at the left plate? Consider only the electrons A and B’s interactions with the constant field between the plates, ignoring any relativistic effects.
A. vA>vB
B. vA=vB
C.vA<vB
D. The answer depends on the size of the plate separation,d.
E. The answer depends on the magnitude of the charge, Q, on each plate

Relevant Equations

C=QV

I cannot understand. I think that the constant electric fields and the direction the electrons ahead of cannot change the speed, but I can’t be sure about that. I really hope that someone can help me on that, thank you very mouch.

Is there a force acting on each charge? If so, what is it and in what direction? Note that the Earth's gravitational field near the Earth's surface is also constant. Can you draw a parallel between the two situations?
