A researcher is developing a highly sensitive air-filled parallel-plate capacitor with a capacitance of 0.8 F for use in a precision measurement device. To keep the design compact, the researcher decides to limit the plate area to 1.5 cm². What should be the separation between the plates to achieve this capacitance? Is such a design practically feasible?

• A. 1.7 × 10^-15 m; No, this is not practically feasible
• B. 1.7 × 10^-15 m; Yes, this is practically feasible
• C. 4.2 × 10^-15 m; No, this is not practically feasible
• D. 4.2 × 10^-15 m; Yes, this is practically feasible
