For this discussion, respond to the 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. you will also need to post a response to at least two of your classmates' posts. also, make sure that your response(s) are substantial and consist of at least 25 words.
