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 9.6 pC. The inner cylinder has radius 0.4 mm, the outer one has radius 5 mm, and the length of each cylinder is 16 cm. What applied potential difference is necessary to produce these charges on the cylinders? (Give your answer in decimal using V as unit)

A variable capacitor consists of two thin coaxial metal cylinders of radii a and b, with (b - a) << a, free to move with respect to each other in the axial direction. The length of the cylinders is L, and the potential difference between the two cylinders is V. Initially, the inner cylinder (radius = a) is completely enclosed by the outer cylinder (radius = b). Using energy methods, find the magnitude and direction of the force on the...
