An electron is accelerated in the uniform field E = 2.0 x 104 N/C between two parallel charged plates (Negative charged plate is on the left and positively charges plate is on the right). The separation of the plates is 1.5 cm. The electron is accelerated from rest near the negative plate and passes through a tiny hole in the positive plate. With what speed does it leave the hole?
