If two capacitors are in series, is their equivalent capacitance lower, or higher, than the individual capacitances?

A uniform magnetic field of 0.60 T is directed to the left, and an electron moves up with a speed of 2.5×106 m/s. The electron has a charge of -1.602×10-19 C, and a mass of 9.11×10-31 kg. What’s the force applied to the electron by the magnetic field? What’s the acceleration of the electron? If the electron continues to act under the influence of this electric field, what will be the radius of its circular path?
