Two air-filled parallel-plate capacitors (C1 and C2) are placed in series. Both capacitors have the same plate area, but the distance between the plates of C1 is twice the distance between the plates of C2. If C1 is equal to 10 μF (microfarads), calculate the equivalent capacitance Ceq of the two capacitors. Quote your answer in μF (microfarads) rounded to one decimal place.
