radii of 2.00 mm, 3.00 mm, and 8.00 mm. The space between the
shells is filled with air. The innermost and outermost cylinders
are connected at one end by a conducting wire. Find the capacitance

Two conducting concentric spheres (shells)have radii R1 = 10 cm and R2 = 20 cm. Both spheres are charged to Q = +20 C. Find: (i) The electric field within the spheres and out of the external sphere. (ii) The potential difference between the spheres. (iii) The electric field profile if the spheres are connected by a thin conducting wire.
Two long, charged, thin-walled, concentric cylindrical shells have radii of 4.3 and 7.0 cm. The charge per unit length is 4.8 × 10-6 C/m on the inner shell and -6.4 × 10-6 C/m on the outer shell. What are the (a) magnitude E and (b) direction (radially inward or outward) of the electric field at radial distance r = 6.1 cm? What are (c) E and (d) the direction at r = 12 cm?
I have built a cavity resonator consisting of two concentric conducting cylinders having radii of 20 cm and 27 cm and an overall length of 36 cm. The space between the cylinders is filled with powdered titanium dioxide, with a dielectric constant of 78. In the following, you may ignore the effects that occur at the ends of the cylinders. (a) Find the capacitance of this device. Note that this requires that you find the electrostatic potential of the device,...
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). Find the electric field everywhere in space. Find the potential difference between the two shells. Which one is...
An air-filled capacitor is formed from two long conducting cylindrical shells that are coaxial and have radii of 21mm and 108 mm. The electric potential of the inner conductor with respect to the outer conductor is - 400 V (k = 1/4πε 0 = 8.99 × 109 N · m2/C2) The energy stored in a 1.0-m length of this capacitor is closest to 5.5 μJ. 2.7 μJ. 1.9 μJ. 7.6 μJ. 3.8 μJ.
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
