An electron falls through a distance d in a uniform electric
field of magnitude E. Thereafter, the direction of the field is
reversed (keeping its magnitude the same) and now a proton falls
through the same distance. Compare, using quantitative reasoning,
the time of fall in each case.
Contrast this situation with that of objects falling freely under gravity.
