A capacitor is formed by two concentric cylinders. The radius of the inner cylinder is 3m and the radius of the outer cylinder is 9m. If the space between these two cylinders is filled with porcelain (κ=6.5) and the capacitor is attached to a 100V battery, determine the charge that will be stored in the capacitor.

Consider two concentric insulating cylinders of infinite length. The inner cylinder is solid with radius R, while the outer cylinder is a hollow shell with inner radius a and outer radius b. Both cylinders have the same volume charge density of +ρ. Using Gauss’s Law, find the electric field as a function of r (where r = 0 at the central axis) in the interval a ≤ r < b. Note: Your final equation should be in terms of given...
