A proton and an electron are moving with the same velocity v perpendicular to a uniform
magnetic field B. Answer the following (explaining the answer):
a) What kind of trajectory each particle follows? (Draw it)
b) Is the value of an electric field E the same for both particles if we want it to make the particles move following a straight-line trajectory? Why?
c) What’s the kinetic energy change before and after applying the electric field?
Data: Proton mass is, approximately, 1836 times electron’s mass.
