Motion of charged particles in electric and magnetic fields

Click For Summary

Homework Help Overview

The discussion revolves around the motion of charged particles, specifically electrons, in electric and magnetic fields, as illustrated by the behavior of an electron beam in a teltron tube under varying high tension voltages. The participants explore the effects of electric fields on charged particles and light waves.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants discuss the relationship between the EHT voltage and the deflection of the electron beam, questioning how the deflection changes with increasing voltage. There is also inquiry into the direction of the EHT potential difference relative to the electron beam and its function.

Discussion Status

The discussion includes attempts to clarify the motion equations relevant to the problem. Some participants express uncertainty about the effects of electric fields on light waves, and one participant indicates they have resolved their understanding.

Contextual Notes

There is mention of the need to consider equations of motion, and some assumptions about the effects of electric fields on light waves are being questioned. The original poster's queries suggest a lack of complete information regarding the specific effects of voltage changes.

Homework Statement


1) Describe and explain what happens to the electron beam on the screen of a teltron tube as the EHT(electrical high tension) voltage increases from 3000V to 3500V.
2)What is the effect of E field on light waves?

Homework Equations

The Attempt at a Solution


1) The beam deflects more as the voltage increases(?? but how much more)
2)No effect?
 
Physics news on Phys.org
1) What is the direction of the EHT potential difference wrt the direction of the electron beam ? (In other words: what's the function of this EHT ?)

2) Because ?
 
You need to consider what the equations of motion are and write these down.
 
Thank you, I have figured it out:smile:
