An electron is moving through a magnetic field whose magnitude is 8.70 × 10-4 T. The electron experiences only a magnetic force and has an acceleration of magnitude 3.50 × 1014 m/s2. At a certain instant, it has a speed of 6.80 × 106 m/s. Determine the angle θ (less than 90°) between the electron’s velocity and the magnetic field.
