1. Electrons start from rest and are accelerated east by two plates (parallel to the north/south directions) through a potential difference. They then pass into a second set of parallel plates 1.2 cm long (parallel to the cast west direction). When the electrons leave the second set of plates they are moving at 3.0 x 10 m's [E 30 N]. You may ignore gravity. (For this question but not in the real world!) Find the potential difference across the first set of plates and the electric field between the second set of plates. 1.2 cm Path of electron
