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 thatd 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 :\ty = h/2000\tan undetermined value since E is unknown\ty = h/43\tnowhere equal, they move in opp directions
