Explaining Why Gas Conducts Electric Fields

AI Thread Summary
The gas in the tube becomes conducting only when the electric field reaches a specific strength, approximately 35 N/C, because this threshold provides sufficient force to ionize the gas particles, allowing them to carry an electric current. The transition from non-conductive to conductive occurs as the electric field strength increases, enabling the gas molecules to gain enough energy to move freely. Electric fields naturally flow from higher potential to lower potential due to the fundamental behavior of charged particles, which move in response to the force exerted by the field. The discussion highlights the need for clarity regarding the specific gas and tube conditions to fully understand the phenomenon. Understanding these principles is crucial for applications involving gas conduction in electric fields.

Homework Statement


Explain why the gas becomes conducting only when the electric field in the tube reaches certain value?
2) why does fields does from higher potential to lower potential?

Homework Equations


F=QE

The Attempt at a Solution


If we increase the E then the Force will also increase so I think the gas needs certain amount of force for it to move to other end. I am not sure If I am right.

The problem statement is incomplete. What gas? What tube?
 
A certain gas in a tube is subjected to an electric field of increasing strength. The gas becomes conducting when the electric field reaches a strength of 35NC^-1
 

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...
