b.tchy question - syclotron or whatever (1 Viewer)

[tooheyz]

just wanna say that that synchotron thingy question was a bitch... i had no bloody idea so i made up crap like - the magnetic field has to increase with the increase in velocity

MuahUAau - 4 marks lost guaranteed.

Actually I thought it was a great question. You had to equate centripetal force with magnetic force and then discuss how since everything else is a constant you have to increase B to keep r constant

 

[Ragerunner]

that is correct

using formula

F = mv^2/r

F = qvbsintheta

 

[tooheyz]

ah wellz... i stuffed up that question. i used f=blvsin0

LOL mate im a looser

 

[Jumbo Cactuar]

Actually it would be more appropriate to say you increase the electrical energy of the syncotron (whateva)

 

[countrydude]

what qn was that? lol i cant even rember

 

[Ragerunner]

Last question

 

[Constip8edSkunk]

but ut asked for magnetic field strength so u say that instead of electrical energy, did any1 also mention mass dilation?

 

[Inhuman]

I did... put it on the the left side of the equation with the velocity and said it increases so B has to increase more

[~Dreamer]

i said it had to increase as well..u know what else was a bitch q 16 - for some reason that screwed me up a fair nit...other than that it was ok...

Yep

I didn't mention mass dilation

I just rearranged it and said because v increases, B has to increase.

Would that get me at least 2-3? -_-

 

[dnt stop runnin]

yeh i equated the centripetal force formula witht he qvb thing...talked about mass dilation and also e-mc sqaured

Umm that's one of the main points of the question.

As mass increases, force must increase. Velocity is part of it though...

 

[smeyo]

yeah i talked about mass dilation since near c mass increases which means energy increases thus b must also increase, thus it used a lot of quantitative formulas to express the corresponding things....

 

[ND]

Yep i talked about mass dilation. Instead of being F=mv^2/r, it would be F=mv^2/sqrt(1-v^2/c^2)r.

that's not really true though

synchotrons don't have one big field
they boost like linear accelerators

the path of the partical isn't really a circle, more like a polygon

Polygon? Polygons aren't curved.

Wow someone agrees with me!!!

Yes, it depends on the way the electron is accelerated around the synchrotron. I used F=ma in my other explanation, and I'm glad someone finally agrees with that as they boost LIKE LINEAR ACCELERATORS.
