    Given information:


    • Anode voltage (Va) = 3000 V

    • Deflection plate length (l) = 3 cm

    • Distance between deflection plates (d) = 7 mm

    • Screen distance from the center of plates (L) = 35 cm

    • Deflection of beam (y) = 4 cm

    • Overall gain of amplifiers (G) = 100



    Calculations:

    The electric field (E) between the plates can be calculated as:
    E = Va / d

    The force on the electron beam (F) due to the electric field can be calculated as:
    F = eE

    Where e is the charge of an electron.

    The deflection of the beam (y) can be calculated as:
    y = (F/2m)*(l/d)^2*L^2

    Where m is the mass of the electron.

    By substituting the values, we get:
    y = (eVaGL^2)/(2md^2)

    Input voltage (Vin) required to deflect the beam through 4 cm can be calculated as:
    Vin = y / (EGL)

    By substituting the values, we get:
    Vin = (4*10^-2 * d^2 * m)/(e*L^2*G)

    Final answer:

    By substituting the values, we get:
    Vin = 1.6 V (approx.)

    Therefore, the required input voltage to deflect the beam through 4 cm is between 1.5 V and 1.7 V (approx.).
