5: Two solid spheres of radius R each have a total charge Q. Sphere A is a conductor and sphere B is an insulator with the charge spread out evenly throughout its volume. The spheres are far from each other so they do not influence each other. Compare the magnitudes of the electric fields at T = for each sphere. Specifically, which is larger and why? Are they zero or nonzero? Explain. Similarly, compare the electric fields at r =...
A solid conducting sphere with radius R centered at the origin carries a net charge q. It is concentrically surrounded by a thick conducting shell with inner radius a and outer radius b. The net charge on the outer shell is zero. (a) What are the surface charge densities sigma at r = R, r = a, and r = b? b) What is the potential V of the inner sphere, assuming a reference point at infinity. Assume now the...
A conducting sphere with radius R is centered at the origin. The sphere is grounded having an electric potential of zero. A point charge Q is brought toward the sphere along the z- axis and is placed at the point ะ-8. As the point charge approaches the sphere mobile charge is drawn from the ground into the sphere. This induced charge arranges itself over the surface of the sphere, not in a uniform way, but rather in such a way...
