[QUOTE="ehild, post: 4947495, member: 481"] 10^-13 in what units? No, it is not right. Think: Forces of the same magnitude act on both particles, F=qE. And you correctly wrote that the acceleration is a=qE/m. m[SUB]e[/SUB]=9,11x10[SUP]-31[/SUP]kg. m[SUB]p[/SUB]=1.67x10[SUP]-27[/SUP]kg. The ratio of the masses m[SUB]p[/SUB]/m[SUB]e[/SUB]=1833. What is the ratio of the accelerations? Again you wrote correctly, that the distance traveled by one particle is x=a/2 t[SUP]2[/SUP]. They travel for the same time. So what is the ratio of the distances they travelled? [/QUOTE]
