booyah 20190402 05:25:52  I have always thought the \"cyclotron frequency\" referred to the angular frequency, so I left out the 2pi. I feel like ETS should have made which type of frequency they were referring to in the question statement more clear   TigerTed8 20070915 11:59:45  I get the correct formula, but I don't know how to plug in the numbers correctly. Can anyone advise?

The real trick to remember here is that this Bfield here is in mks Tesla and happily that is what ETS provides us with; with a Pi in it, to boot! The Pi's will cancel into the angular frquency and the 1600 will cancel out the 1.6 in the electron charge so you'll get something like
m = [2(1.6E19Coulomb)(Pi/4Tesla)]/[2Pi(1600Hz)] =1/4 E 22 =2.5E23 kg=> (A)
Drill every day with ETS problems and PERTINENT formulas, get plenty of sleep, eat right, keep a good attitude and good luck!
