Consider the limit of large distances, where a finite charged rod is observed at a distance that is very large when compared to the length of the rod.

In this situation, the electric field best resembled that of a ...

a)point charge ... it goes like r-2

b) infinite line ... it goes like r-1

c) electric dipole ... it goes like r-3

d) infinite plane ... it is constant

none of the above ... it is zero
