4. An electron (mass m= 9.11 x 10-3¹ kg) is accelerated in the uniform field E (E 1.45 × 10⁰ N/C) between two thin parallel charged plates. The separation of the plates is 1.60 cm. The electron is accelerated from rest near the negative plate and passes through a tiny hole in the positive plate, Figure. (a) With what speed does it leave the hole? (b) Show that the gravitational force can be ignored.
