Force on a Moving Charge: 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. Calculate the magnitude of the acceleration of the electron. (e = 1.60 × 10-19 C, me1 = 9.11 × 10-31 kg)
