Definition of Radius of a charged particle orbit
Check what you remember
Read the wording for your board, then hide it and explain Radius of a charged particle orbit in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Equating BQv to mv²/r gives r = mv/(BQ), so the radius depends on mass, speed, flux density and charge.
