A capacitor is constructed of two concentric conducting cylindrical shells. The radius of the inner cylindrical shell is 2.37 x10-3 m, and that of the outer shell is 2.47 x 10-3 m. When the cylinders carry equal and opposite charges of magnitude 2.0 x 10-10 C, the electric field between the plates has an average magnitude of 3.8 x 104 V/m and is directed radially outward from the inner shell to the outer shell. Determine (a) the magnitude of the potential difference between the cylindrical shells and (b) the capacitance of this capacitor.

Concentric Cylindrical Conducting Shells 1 An infiinitely long solid conducting cylindrical shell of radius a = 4.8 cm and negligible thickness is positioned with its symmetry axis along the z-axis as shown.

Two very long concentric conducting cylindrical shells are arranged as seen below. The inner shell has a radius a, and the outer shell a radius b. Each shell has a length L. A charge of -Q is spread over the inner shell and a charge of +Q resides on the outer shell. Ignore fringe fields (e.g. assume each cylinder is very long).

A capacitor is composed of two cylindrical conducting shells. The inner shell has a radius A, is centered inside the outer shell and has a positive surface charge density +3s. The outer shell has radius B = 3A and negative surface charge density -s. Assume the length of the conductors is ?infinitely? long compared to the radius B so that you can ignore all edge effects.
