Rank the magnitudes of the forces exerted on the following particles from largest to smallest. In your ranking, display any cases of equality. (Use only ">" or "=" symbols. Do not include any parentheses around the letters or symbols.)
(a) an electron moving at 1 Mm/s perpendicular to a 1-mT magnetic field
(b) an electron moving at 1 Mm/s parallel to a 1-mT magnetic field
(c) an electron moving at 2 Mm/s perpendicular to a 1-mT magnetic field
(d) a proton moving at 1 Mm/s perpendicular to a 1-mT magnetic field
(e) a proton moving at 1 Mm/s at a 45° angle to a 1-mT magnetic field
