Calculating Electric Field Intensity Between Capacitor Plates

To find the electric field intensity between the plates of a capacitor, we can use the formula:

Electric field intensity (E) = Q / (ε * A)

Where: - Q = charge on the plates - ε = permittivity of the material between the plates - A = area of the plates

Given: - Area of each plate (A) = 401 cm^2 = 401 * 10^-4 m^2 - Charge on the plates (Q) = 1.42 μC = 1.42 * 10^-6 C

Using the formula, we can calculate the electric field intensity.

Calculation

Electric field intensity (E) = Q / (ε * A)

From the provided information, the permittivity of the material between the plates is not given. However, in a vacuum, the permittivity (ε) is approximately 8.85 * 10^-12 F/m.

Substituting the given values: E = (1.42 * 10^-6) / (8.85 * 10^-12 * 401 * 10^-4)

Calculating: E ≈ 4.01 * 10^3 N/C

Conclusion

The electric field intensity between the plates of the capacitor is approximately 4.01 * 10^3 N/C.
