Okay. F=qE and Q=CV gives F=CVE so that would give me the force that affects the electron beam between the plates. But it still doesn't make much sense, there must also be a magnetic field that i have to consider.

An electron beam is send perpendicular onto an electric field between two capacitor plates. The electrons got their kinetic engergi by being accelerated through a potential difference V. The potential difference between the capacitor plates are also V. The distance between the plates is d, and...
