An electron gun fires a beam of electrons at 2.0 × 10
There is a uniform electric field between the plates of 1.5 × 10
Ignore gravitational effects on the electron beam.
- Show that the acceleration of an electron between the parallel plates is 2.6 × 10

- Show that the vertical displacement of the electron beam at the end of the parallel plates is approximately 8.1 mm. (2 marks)
--- 4 WORK AREA LINES (style=lined) ---
- How far from point
will the electron beam strike the screen? (3 marks)
