Motion of charged particles in electric and magnetic fields

AI Thread Summary
As the EHT voltage in a teltron tube increases from 3000V to 3500V, the electron beam experiences greater deflection due to the increased electric field strength. The direction of the EHT potential difference is crucial as it influences the trajectory of the electron beam. The effect of the electric field on light waves is generally negligible, as light is not significantly affected by electric fields in the same way charged particles are. Understanding the equations of motion for charged particles helps clarify these effects. Overall, the interaction of electric fields with charged particles is significant, while light waves remain largely unaffected.

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?

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:
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
