Austration 1.14 An electron accelerated through a potential difference of 2.5 kV, moves horizontally into a region of space in which there is a downward directed uniform electric field of magnitude 10 kVm-1. a. In what direction must a magnetic field be applied so that the electron moves undeflected? Ignore the gravitational force. What is the magnitude of the smallest magnetic field possible in this case? b. What happens if the charge is a proton that passes through the same combination of fields?
