a)
a) The diagram below illustrates an experiment with electrons. A beam of electrons is created using an electron gun, and deflected using an electric field.
Explain how the electron gun creates a beam of electrons. Add to the diagram if that will help your explanation.
The electric field which deflects the beam is created by applying a potential difference of 2500 V across plates 9.0 cm apart. Show that the vertical acceleration of the electrons due to this field is about 5 × 1015 m s–2.
