6. Spinning Cylinder A cylinder of radius R and infinite length is made of permanently polarized dielectric. The polarization vector P is everywhere proportional to the radial vector r, such that P = ar, where a is a positive constant. The cylinder rotates around its axis with an angular velocity w This is a non-relativistic problem where wR< c. a) Find the electric field E at a radius r both inside and outside the cylinder. b) Find the magnetic field...
2) In figure, a top view of a solid conducting cylinder with radius a - 1 em, whose center is at the origin of the coordinate system and +z axis is towards out of page. It is concentric with a hollow cylindrical conductor of inner radius b 3 cm and outer radius c 5 cm. Both cylinders have L-5 m lengths which can be assumed to be infinitely long since L > c. The solid cylinder has total net charge...

FAO Figure 1 2. A thin wire of length L has a uniform charge density +1.A cylindrical Gaussian surface of radius d is drawn with the wire along its central axis, as shown above. Point P is located at the center of one end of the cylinder, a distance d from the end of the wire. Point Q is on the edge of the cylinder directly above the center of the wire, as shown above. A student says, "Gauss's law...
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...
