We calculate the electric field strength in a flat air capacitor by the formula:
E = U / l, where U is the voltage across a flat air capacitor (U = 500 V), l is the distance from a given point to the capacitor (l = 8 mm = 8 * 10-3 m).
Let’s calculate the electric field strength:
E = U / l = 500 / (8 * 10-3) = 62,500 V / m.
Answer: The electric field strength in a flat air capacitor is 62,500 V / m.
