2. Gauss' Law See Figure 1. A solid, conducting sphere of radius a has total charge (-)2Q uniformly distributed along its surface, where Q is positive. Concentric with this sphere is a charged, conducting spherical shell whose inner and outer radii are b and c, respectively. The total charge on the conducting shell is (-)8Q. Find the electric potential for r < a. Take the potential out at infinity to be 0.
Figure 27.33 shows a charge (+ q) on a uniform conducting hollow sphere of radius a and placed at the center of a conducting spherical shell of inner radius b and outer radius c. The outer spherical shell carries a charge (- q). What is the charge on the outer surface (c) of the shell. Use Gauss' law to find E(r) at positions: within the conducting spherical (r < a); between the sphere and the shell (a<r< b); inside the...
A small, solid conducting sphere of radius r1 sits inside a hollow conducting spherical shell of inner radius r2 and outer radius r3. A potential difference of magnitude V is placed across the inner and outer conductors so that there is a net charge of -Q on the inner conductor and +Q on the outer conductor. Suppose a thin but finite thickness conducting shell was placed between the sphere and the outer shell. This extra shell is electrically isolated. Would...
