Product description

A monoenergetic beam of electrons that has passed through an accelerating potential difference of 20 kV illuminates a spot with a radius of 10^-3 cm in the center of the screen of a cathode ray tube, the length of which is 0.5 m. Using the uncertainty relation, determine how many times the uncertainty of the electron coordinate on the screen is in the direction perpendicular to the tube axis, less than the spot radius.
