Question:

An electron is accelerated horizontally from rest in a television picture tube by a potential difference of 5500 V. It then passes between two horizontal plates 6.5 cm long and 1.3 cm apart that have a potential difference of 250V (Fig 17-31). At what angle θ will the electron be traveling after it passes between the plates?
