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
