Question

Deflection of electron in an electric field lab. The objective of this lab says "to observe the effects of an electric field on the motion of electrons and to show a relationship between the field strength and the distance the electrons are deflected."

We do measurements at three different accelerating voltages: 250, 375, and 500. We move the electron 2 mm up and down at a time in the cathode tube ray. I understand my data and the formulas, but I do not actually understand what we're looking for in this lab and I'm having trouble understanding what the actual objective is. Can someone please explain?

Explanation / Answer

A charged particle experiences a force when it is in a region where there exists an electric field.

so it does not follow straight path it go by a parabolic path .
