A particle with mass m and charge q has been accelerated throughan electric potential difference of V and is about to enter arectangular area with uniform magnetic field B. Your goal is to usethe magnetic field to completely turn the particle around so it’sheading in the opposite direction but also to make the field assmall (in physical space, dimension wise) as possible. What shouldthe minimum dimensions be (long side and short side) of therectangular magnetic field?
