A uniform magnetic field of magnitude 0.80 T in the negative z-direction is present in a region of space, as shown in the figure. A uniform electric field is also present and is set at 7.6 x 104 V/m in the +y-direction. An electron is projected with an initial velocity of 9.2 x 104 m/s in the +x-direction. The y-component of the net initial force on the electron is closest to which of the following?
