An electron (mass m = 9.11E-31 kg) is accelerated in the uniform field E (E = 1.64E+4 N/C) between two parallel charged plates. The separation of the plates is 1.33 cm. The electron is accelerated from rest near the negative plate and passes through a tiny hole in the positive plate, as seen in the figure above. With what speed does it leave the hole?
