An electron moves with a speed of 80 x 106 ms along the

Question

An electron moves with a speed of 8.0 x 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^o to the +x-axis and lying in the xy-plane. (1 eV = 1.60 x 10^-19 C, mel = 9.11 x 10^-31 kg) Calculate the magnitude of the magnetic force on the electron.
