Answer 2

To find the distance between the plates of a capacitor, we can use the formula:

C = (ε₀ * εᵣ * A) / d

Where: - C is the capacitance of the capacitor - ε₀ is the vacuum permittivity (8.854 x 10^-12 F/m) - εᵣ is the relative permittivity of the dielectric material (in this case, paraffin with a value of 2) - A is the area of each plate - d is the distance between the plates

Given: - Voltage (V) = 150 V - Area (A) = 120 cm² = 0.012 m² - Charge (Q) = 5 nC = 5 x 10^-9 C - Relative permittivity (εᵣ) = 2

First, let's calculate the capacitance using the formula:

C = Q / V

C = 5 x 10^-9 C / 150 V

C = 3.33 x 10^-11 F

Now, we can rearrange the formula for capacitance to solve for the distance (d):

d = (ε₀ * εᵣ * A) / C

Substituting the given values:

d = (8.854 x 10^-12 F/m * 2 * 0.012 m²) / (3.33 x 10^-11 F)

d = 0.067 m

Therefore, the distance between the plates of the capacitor is approximately 0.067 meters.
