    Motion Protons
AI Thread Summary
When two protons travel parallel at the same velocity, an observer moving with them perceives them as stationary, experiencing only electrical attraction. In contrast, a stationary observer sees the protons in motion, generating magnetic fields that influence each other's trajectories. This discrepancy arises because the observers are in different inertial frames, leading to different interpretations of forces acting on the protons. The confusion stems from the relativistic effects, particularly time intervals, which affect the perceived forces. Understanding these differences is crucial for resolving the apparent contradiction in observations.

hello, this is a question from the book that i got no idea on it

'When two proton are traveling at same velocity parallel to each other, like this (respect to groung)

proton A >>>
proton B >>>

an observer is also travel at the same speed along their path. according to him, two proton are stationary, so the only force is the electrical attraction

Another observer who is stationary will observe two proton moving, both create magnetic field which influence the motion of the other proton

What do you say?

I thought the two observer are both in inertial frame, therefore should applied the same law. but the situation is different to that? i am totally confused.

Can anyone help me? thanks very much

I think it's that the time interval is also different,so the effect of the electric force is defferent.You can calculate it.
 

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'

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...
