A (nonconstant) harmonic function takes its maximum value and its minimum value
on the boundary of any region (not at an interior point). Thus, for example, the
electrostatic potential V in a region containing no free charge takes on its largest
and smallest values on the boundary of the region; similarly, the temperature T of a
body containing no sources of heat takes its largest and smallest values on the surface
of the body. Prove this fact (for two-dimensional regions) as follows: Suppose that
it is claimed that u(x, y) takes its maximum value at some interior point a; this
means that, at all points of some small disk about a, the values of u(x, y) are no
larger than at a. Show by Problem 36 that such a claim leads to a contradiction
(unless u = const.). Similarly prove that u(x, y) cannot take its minimum value at
an interior point

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
