43. An electron that has received its speed under the influence of a voltage of 6000 V flies into the middle between the plates of a flat capacitor parallel to them. What is the smallest voltage you need to apply to the capacitor so that the electrons do not fly out of it? The length of the plates of the capacitor is 12 cm, the distance between the plates is 2 cm.
