question

A proton moves in the +z-direction after being accelerated from rest through a potential difference V. The proton then passes through a region with a uniform electric field E in the +x-direction and a uniform magnetic field B in the +y-direction, but the proton’s trajectory is not affected. If the experiment were repeated using a potential difference of 2V, the proton would then be

choices

  1. deflected in the +x-direction
  2. deflected in the -x-direction
  3. deflected in the +y-direction
  4. deflected in the -y-direction
