2. (25 points) Two concentric spheres have radii Ri and R2 (R2 > Ri). The potential everywhere on the surface of the inner sphere is zero. On the surface of the outer sphere the potential is given by V(R2,0-10 cos2 θ, where Vo is a constant and θ is one of the spherical coordinates. What is the potential in the region Ri < R2?

There are two spheres with uniformly distributed charges -q and +q through their volumes. The spheres have radii R, and 2R respectively. Point P lies on the surface of the larger sphere on a line connecting the centers of the spheres. Find the electric field at point P if -q=+q= 30 fC, and R=2cm.
See Figure 1. A solid, conducting sphere of radius a has total charge (-)2Q uniformly distributed along its surface, where Q is positive
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.

4 Two spherical conductors (Homework #3) Two spherical conductors of different radii (Ri and R2) are connected by along fine conducting wire. Let's assume Ri << R2, the smaller sphere carries the total charge 0 (with surface chargé density o) and the larger sphere carries the total charge Q2 (with surface charge density ). a) Remember that the potential is always constant on and in the conductor. Using th is fact, show that the ratio of the charge is given...

A conductive sphere has a total charge Q uniformly distributed over its surface except at a point A, where there is no charge. Assuming that the point A has a 1/50 of the total area of the sphere. a) find an expression for the total electric field of the system on the axis between the center of the sphere and the center of the point A. b) calculate the electric filed at points r = 0, r = 0.9R, r...

A spherical shell of radius R1=4 cm carries a total charge q1=10 C that is uniformly distributed on its surface. A second, larger spherical shell of radius R2=24 cm that is concentric with the first carries a charge q2=6 C that is uniformly distributed on its surface. Calculate the strength of the electric field at r=12 cm. (Your result must be in multiples of 1013 N/C. That means if, for example, you get a result of a × 10 13...

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...
