Question
Transcribed Image Text: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?
