What is the capacitance? Use 8.854x10-12 F/m for the permittivity of free space. VO AEQ C =What applied potential difference is necessary to produce these charges on the cylinders? * . AEd} A capacitor is made from two hollow, coaxial, iron cylinders, one inside the other. The inner cylinder is negatively charged and the outer is positively charged; the magnitude of the charge on each is 105 p0 . The inner cylinder has a radius of 0.700 mm , the outer one has a radius of 4.80 mm , and the length of each cylinder is 14.0 cm
