An electron moving horizontally to the right with speed v enters a region where a uniform magnetic field exists, pointing out of the page/screen with magnitude B. What should the direction of an electric field E be so that the electron continues moving in a straight line with constant velocity? a. Down (top of screen/paper to bottom of screen/paper) b. Up (bottom of screen/paper to top of screen/paper) c. Out of screen/paper d. Into screen/paper e. To the left
