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 0.250 mm, the outer one has a radius of 5.00 mm, and the length of each cylinder is 22.0 cm.1.what is the capacitance? use 8.854×10−12 f/m for the permittivity of free space.2.what applied potential difference is necessary to produce these charges on the cylinders?
