Basic Coulomb's law tells us that the electric field of a point
charge q, E=ke q/r2, scales with distance r
as 1/r2: when the distance increases by a factor of 2,
the magnitude of the field decreases by a factor of 4. We can write
this as E(r) ∝ 1/r2. An interesting and practically
important question is how the electric field of a group of charges
scales with distance (asymptotically) far away from the group. The
