An electron that has a velocity with x component 2.6 × 106 m/s and y component 2.4 × 106 m/s moves through a uniform magnetic field with x component 0.029 T and y component -0.14 T. (a) Find the magnitude of the magnetic force on the electron. (b) Repeat your calculation for a proton having the same velocity.
