Question

Calculate the electric field between the plates of an air-filled capacitor with a 20.0-V potential difference.

a) 1.0 × 10^4 N/C
b) 2.0 × 10^3 N/C
c) 5.0 × 10^3 N/C
d) 1.0 × 10^3 N/C

Answer 1

Without the distance between the capacitor plates, we cannot calculate the electric field. If we assume a distance of 2 cm, the electric field would be 1.0 × 10^3 N/C.

Step-by-step explanation:

To calculate the electric field between the plates of an air-filled capacitor with a 20.0-V potential difference, we can use the formula for the electric field E:

E = V/d

Where V is the potential difference and d is the distance between the plates. As the distance d is not given in the question, we are unable to provide a specific value for the electric field. Normally, d would need to be provided to make a calculation. However, if we assume the distance to be 2 cm (which is common in textbooks as an example), using the formula:

E = 20.0 V / 0.02 m = 1.0 × 103 N/C

Therefore, the correct answer, assuming a 2 cm distance, would be (d) 1.0 × 103 N/C.
