A proton moves at a speed of 1,605 m/s in a direction perpendicular to a magnetic field with a magnitude of 0.58 T. If the proton is replaced with an electron, how will the magnitude of the force change? |Felectron| |Fproton|= How will the direction of the force change? The force on the electron will be in the opposite direction as the force on the proton. The force on the electron will be at a 45° angle to the force on the proton. The force on the electron will be in the same direction as the force on the proton. The force on the electron will be perpendicular to the force on the proton.
