Acapacitor 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 12.0 pc . the inner cylinder has a radius of 0.600 mm , the outer one has a radius of 7.00 mm , and the length of each cylinder is 12.0 cm . (a) what is the capacitance? (b) what applied potential difference is necessary to produce these charges on the cylinders?
