An electron with kinetic energy K moving along the positive direction of an x axis enters a region in which a uniform electric field of magnitude E is in the negative direction of the y axis. A uniform magnetic field is to be set up to keep the electron moving along the x axis, and the direction of the field is to be chosen to minimize the required magnitude of the field. What is the magnitude of the magnetic field
