Show that the electric field of a (perfect) dipole (Eq. 3.103) can be written in the coordinate-free form
The potential at the surface of a sphere (radius ) is given by
,
Where is a constant. Find the potential inside and outside the sphere, as well as the surface charge density on the sphere. (Assume there's no charge inside or outside the sphere.)
A rectangular pipe, running parallel to the z-axis (from to ), has three grounded metal sides, at and The fourth side, at , is maintained at a specified potential .
(a) Develop a general formula for the potential inside the pipe.
(b) Find the potential explicitly, for the case (a constant).
In Ex. 3.9, we obtained the potential of a spherical shell with surface
charge. In Prob. 3.30, you found that the field is pure dipole outside; it's uniforminside (Eq. 3.86). Show that the limit reproduces the deltafunction term in Eq. 3.106.
In Ex. 3.2 we assumed that the conducting sphere was grounded ( ). But with the addition of a second image charge, the same basic modelwill handle the case of a sphere at any potential (relative, of course, to infinity). What charge should you use, and where should you put it? Find the force of attraction between a point charge q and a neutral conducting sphere.
