An electron is fired horizontally at a velocity of 3.5 x 106 mfs in between two oppositely charged plates. The electron enters the system 2.0x10'3 m from the bottom plate as shown below. The plates have a separation of 1.0 x 10'2 m and a potential difference of 2.0 x 102 V across them. How far along does the electron travel horizontally before it collides with a plate? 1.0 1 10\" m
