A proton traveling with speed 3105 m/s in the +x direction passes through a region in which there is a uniform magnetic

field of magnitude 0.6 T in the +y direction. You want to keep the proton traveling in a straight line at constant speed. To

do this, you can turn on an apparatus that can create a uniform electric field throughout the region. What (vector) electric

field should you apply?
