Yes, and from what I understood, your position was two co-moving electrons experience an attractive magnetic force towards each other. Or at least that's what I thought jartsa was telling me. And I thought I had it down until someone on another forum mentioned the argument I will elaborate on...
I've just been told two co-moving electrons will not experience a magnetic force that pulls them towards each other. Is this true?? I thought this was like the main reason for two wires with identical currents attracting ...
That gives me a formula but it doesn't answer the question for me. If you don't want to tell me just say you don't feel like figuring it out. jartsa was helpful but you are not
Ah you're right.
I have a question about the magnetic force. If the strength of the electric repulsion between two electrons co-moving at 87% the speed of light is 1 then is the strength of the magnetic attraction between them 0.5? And if the electrons are moving in opposite directions is the...
In one frame the ratio is 0.25 which is harder to work with than mine which is 0.5. Not a big difference but I want to keep things simple as possible!
Sure it does, the ratio is all that matters and you must assume the segment I've shown is representative of the ratio of the entire wire
DrGreg's diagram is not suited for my purposes since there are too many particles and also, not a simple ratio of electrons to protons in each frame. Is mine correct?
I actually just solved my problem to my own satisfaction. Here is my reasoning. The two spaceships accelerate at the same time in S, so their separation (between midpoint of each spaceship) remains constant, while the length of each spaceship (and the string) contracts. This breaks the...
It seems to demonstrate the finite speed of light. What does it have to do with relativity?
What information is lacking? The rate of acceleration? Direction?
A point-particle soccer ball (electron) is kicked (accelerated) on a soccer field (particle accelerator). Does not a gravitational field appear in the electron frame?
You could not. You'd be accelerating downwards.
So it's impossible to answer my question, do the two rocks agree on what...
If I kick a soccer ball, does not a gravitational field suddenly (poof!) appear in the soccer ball frame?
The rocks are hovering in the sense that the ground is preventing them from falling. It seems to me the situations are equivalent. They are experiencing 1G which could be described...
The gravity field is uniform and just appears, poof! Like that.
A survey of opinion at CERN, according to Wikipedia, showed most theoretical physicists misunderstood Bell's paradox also. So I strongly advise you not to be condescending. I can use gravity since it's equivalent to...
