An electron is moving through a magnetic field whose magnitude is8.60 multiplied by10-4 T. The electron experiences only a magnetic forceand has an acceleration of magnitude 3.20multiplied by 1014m/s2. At a certain instant, it has a speed of6.10 multiplied by106 m/s. Determine the angle θ (less than90°) between the electron's velocity and the magnetic field.
