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?

In Bohr's model of the hydrogen atom, let $$R, V, T$$ and $$E$$ represent the radius of the orbit, speed of the electron, time period of revolution of electron and the total energy of the electron respectively. The quantity proportional to the quantum number n is
