What are the three main components of a cathode ray tube ? Explain the function of each component. Draw a neat labelled diagram of cathode ray tube.

Describe briefly the effect of an electric field, on a beam of electrons.

The diagram below shows a cathode ray tube in which the arrow indicates a beam of charged particles approaching an electric field between the plates $A$ and $B$.

Name the charged particles.
