controls:

acceleration voltage Va
plate voltage Vp

$E=\frac {V_{\text p}}{\text d}=$ ${0}$ $\frac {\text V}{\text m}$

Schematic layout of the experiment

Use the experiment to test and rate your hypotheses!

- the higher Vp, the bigger the deflection
- the lower Va, the bigger the deflection
Real experiment about deflection of electrons in electric field of a plate capacitor
