A proton and electron moving with the same speed enter the magnetic field of the earth at the same angle (not 90 degrees). State the similarities and differences in the direction and shape of the particles' trajectories.
a) what type of trajectory will each particle follow in the earth's magnetic field?
b) How different will the direction of the proton's trajectory be from the electron's?
c) How different will the shap (radius and/or thread) of the proton's trajectory be from the electron's?
