The cathode and anode of a two-electrode lamp (diode), made in the form of a flat capacitor, are located vertically in the gravitational field. The cathode emits electrons, the speed of which can be considered equal to zero. Determine the vertical displacement S of the electron when flying between the electrodes. The ratio of the charge of an electron to its mass is equal to R; anode voltage V, interelectrode distance d.
