A point dipole p oriented along the z-axis is placed at the center of a spherical cavity of radius R with conducting walls. The walls are grounded.

Find the potential everywhere inside the cavity using the general solution in spherical coordinates,

V(r, theta) = Sigma [A_lr^l + B_l/r^l + 1](cos theta),

with the following two boundary conditions:

V = 0 at r = R and (ii) V rightarrow V_dipole as r rightarrow 0.

The us government wants to allocate billions of dollars in the next 10 years to assure our future energy security. the funds will be spread among a variety of possible energy resources. where do you think the government should put the greatest support: solar energy, wind energy, clean coal, oil exploration, gas exploration, or a combination of sources? are there other efforts that should be explored? support your position with cited information for both questions.
