Task 60277.

A beam of monoenergetic electrons falls on a gap with a width of a = 10 nm. We can assume that if an electron passed through the gap, then its coordinate in the direction transverse to the motion is known with an uncertainty equal to a. To evaluate the resulting relative inaccuracy in determining the momentum if the electron energy is 10 eV.
