Which theory best describes this behavior pattern (which is correlated with higher levels of reported happiness in older adulthood)?

A unifоrm mаgnetic field оf mаgnitude 0.80 T in the negаtive z-directiоn is present in a region of space. A uniform electric field is also present. In the figure, the electric field is set at 27,200 V/m in the positive y-direction. An electron is projected with an initial velocity vo = 3.4 x 104 m/s  in the positive x-direction. The y-component of the initial force on the electron is closest to:
