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 $B$.

State the approximate voltage $V_1$ used to heat the filament.

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 $B$.

State the approximate potential difference $V_2$ applied between the anode and filament.

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 $B$.

What will happen to the beam when it passes through the electric field ? Draw separate diagram to explain your answer.
