this should probably go in the HS section since it is review of some material covered there but.... I'm guessing the same peole brose the two forums so I might as well post it here since it came up in college.(adsbygoogle = window.adsbygoogle || []).push({});

now the questions seems quite straight forward:

for a particle of mass m and charge q, moving in a circular path in a magnetic field B, show that its kinetic energe is proportional to the square of the radius of curvature of its path.

so we have:

r = (mv^2)/qvB

r = mv^2/F

F = ma

F = m((v^2)/r)

r = (mv^2)/(m((v^2)/r))

now.... it all evens out and I'm stuck with nothing.... could someon tell me where I'm going wrong with this
