Help Needed: Magnetism and Electron/Alpha Particle Motion

Click For Summary
SUMMARY

The discussion centers on calculating the frequency ratio of an electron and an alpha particle moving in a magnetic field with the same tangential speed. The key equation for determining the frequency of a charged particle in a magnetic field is essential for solving this problem. Participants emphasize the importance of understanding this equation to derive the frequency ratio effectively. The focus is on applying the principles of magnetism to compare the motion of these two particles.

Homework Statement



Hi guys. I'm stuck at a question that has to do with magnetism and I would really appreciate some help!

The question is:

"An electron and an alpha particle are in a magnetic field and moves in circles with the same tangential speed. Calculate the ratio between the number of revolutions per second that the electron does compared to the alpha particle."

(sorry if it's not 100% correct, since english is not my first language, translated the question from another language...)

Thanks! :)

number of revolutions per second is essentially the frequency...

so if u do know the equation for the frequency of a particle in a magnetic field... you should be able to determine the ratio of frequencies for the alpha particle and the electron!

hmm, ok.. how do I find out that equation then?
