An electron and a $0\mathrm{.}0260$ kg bullet each have a velocity of magnitude $470$ m$/$s$,$ accurate to within $0\mathrm{.}0100\%.$ Within what lower limit could we determine the position of each object along the direction of the velocity? $($Give the lower limit for the electron in mm and that for the bullet in m$.)$
