An air-filled capacitor consists od two parallel plates, each with an area of 7.60 cm2, separated by a distance of 1.70 mm. A 17.0-V potential difference is applied to these plates.
Calculate the surface charge density on the plates

Amanometer is used to measure the air pressure in a tank. the fluid used has a specific gravity of 1.25, and the differential height between the two arms of the manometer is 34 in. if the local atmospheric pressure is 12.7 psia, determine the absolute pressure in the tank for the cases of the
