Oscilloscopes have parallel metal plates inside them to deflect the electron beam. These plates are called the deflecting plates
Alina [70]

Answer:

The capacitance of the deflecting plates is C=1.59 pF.

Explanation:

The expression for the capacitance of the capacitor in terms of area and distance is as follows;

C=\frac{\varepsilon _{0}A}{d}

Here, C is the capacitance, A is the area, d is the distance and \varepsilon _{0} is the absolute permittivity.

Convert the side of the square from cm to m.

s= 3.0 cm

s= 0.030 m

Calculate the area of the square.

A= s_^{2}

Put s= 0.030 m.

A=(0.030)_^{2}

A=9\times10^{-4}m^{-2}

Convert distance from mm to m.

d= 5.0 mm

d=5\times10^{-3}m

Calculate the capacitance of the deflecting plates.

C=\frac{\varepsilon _{0}A}{d}

Put d=5\times10^{-3}m, A=9\times10^{-4}m^{-2} and \varepsilon _{0}=8.85\times 10^{-12}Fm^{-1}.

C=\frac{(8.85\times 10^{-12})(9\times10^{-4})}{5\times10^{-3}}

C=1.59\times 10^{-12}F

C=1.59 pF

Therefore, the capacitance of the deflecting plates is C=1.59 pF.
