How Does Kinetic Energy Affect Electron and Proton Movement?

AI Thread Summary
An electron gains 5.4 keV of kinetic energy (KE) when moving from point A to point B. The discussion raises questions about the KE a proton would acquire under similar conditions, specifically whether it differs due to mass. Additionally, it seeks to determine the speed ratio of the electron and proton at the end of their trajectories, given they have the same KE. The need for clarification on the presence of an electric field affecting the particles' movement is also highlighted. Understanding these concepts is crucial for solving the problem effectively.

Homework Statement



An electron starting from rest acquires 5.4keV of KE moving from point A to point B.
1. How much KE would a proton acquire, starting from rest at B and moving to point B.
2. Determine the ratio of their speeds at the end of their respective trajectories.

I am not for sure

The Attempt at a Solution



I am sorry I don't even have an attempt because I don't even know where to begin. I am so confused on this one.

1. I don't think there is any difference in the amount of KE an electron would get from A to B, but you have to be more specific, is there an electric field somewhere along the path?

2. From the formula for KE, can you tell what are the respective speeds if they have the same KE?
 

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...
