answer with explanation

4. An electron (m = 9.11 x 10-31 kg) is accelerated horizontally from rest in a television picture tube by a potential difference of 5500 V. It then passes between two horizontal plates 6.6 cm long and 1.4 cm apart that have a potential difference of 300 V. At what speed (direction not required) will the electron be travelling after it passes between the plates? [5] VI
