I need to derive the following formula, in relation to the angle between the electron beam and the plates where the beam of electrons hits the plates in a Teltron tube:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]tan \theta = \frac{Eqs_{h}}{mv_{h} ^2}[/tex]

I think I managed to complete about 70% of this, but I need to found out what it is in its entirety!
