Recap - Beam Between Plates

Part of the Electricity and Magnetism section of Coddy's Physics journey. Lesson 16 of 51.

Challenge

An electron enters the space between two plates moving at 2 × 10⁷ m/s, parallel to them. The plates are 0.05 m long, and the field between them is 2000 N/C, pointing down. How far y has the electron moved across the field when it leaves the plates, in millimetres?
