A proton sits at coordinates (x;y) = (0;0) and an electron at (d;h) where d>>h. At time t=0, a uniform electric field E of unknown magnitude but pointing in the +ve y direction is turned on. Assuming that d is large enough that the proton -electron interaction is negligible, the y coordinates of the two particles will be equal (at equal time) at about : y = h/2000 an undetermined value since E is unknown y = h/43 nowhere equal, they move in opp directions

  2. an undetermined value since E is unknown
  3. y = h/43
  4. nowhere equal, they move in opp directions
