Final answer:
The capacitance per square meter for a capacitor with an air gap of 2 mm between its parallel plates can be calculated using the formula C = (ε₀ * A) / d.
Step-by-step explanation:
The capacitance per square meter for a capacitor with an air gap of 2 mm between its parallel plates can be determined using the formula:
C = (ε₀ * A) / d
Where C is the capacitance per square meter, ε₀ is the permittivity of free space (8.85 x 10-12 F/m), A is the area of one plate, and d is the distance between the plates.
By plugging in the appropriate values and converting units, the capacitance per square meter can be calculated.
