The problem is attached, stuck on part d.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

Im given a problem with two horizontal and parallel plates 8cm long 3cm away from each other. An electron is moving through them with a velocity V[itex]_{0}[/itex]. It is also given that the voltage across the plates is 20 Volts and the electron deflects upwards 1.2 cm.

2. Relevant equations

Ive done all the work for parts a, b, and c, which gave me a F[itex]_{electric}[/itex] of 666.67 V/m or 666.67 N/C down, and an acceleration of 1.17 * 10[itex]^{14}[/itex] m/s[itex]^{2}[/itex] up.

3. The attempt at a solution

I have no idea how to even come at this. The only idea I had without being given an initial velocity in any direction is something with the deflection of 1.2 cm, but I dont know how to use that without knowing the amount of time the electron spends between the plates.

Thanks for ANY help.
