An electron moves with a speed of 8.0 × 106 m/s along the +x-axis
It enters a region where there is a magnetic field of 2.5 T, directed at an angle of 60° to the +x-axis and lying in the xy-plane. (1 eV = 1.60 × 10-19 C, mel = 9.11 × 10-31 kg) Calculate the magnitude of
(a) the magnetic force on the electron.
(b) the acceleration of the electron.
