An electron with kinetic energy 2.5 ke V moving along the positive direction of an x axis enters a region in which a uniform electric field of magnitude 10 k V/m is in the negative direction of the y-axis. A uniform magnetic field B→ is to be set up to keep the electron moving along the x-axis , and the direction B→ of is to be chosen to minimize the required magnitude of B. In unit-vector notation, what B should be set up?
