The Electric Field of a Continuous Charge Distribution Not practical to keep track of every electron. It is easier to consider a continuous matter and talk about charge density. Let’s consider an object of length L such as plastic rod or metal wire QC Lm λ ⎡⎤ = ⎢⎥ ⎣⎦

Charged Surfaces 2 [/ ] Q Cm A η= Strategy to find the electric field of a continuous charge distribution: Divide the total charge Q into many small point-like charges Calculate the field from a single point-like charge Calculate the net field by summing the fields of all the small point-like charges

A piece of plastic is uniformly charged with surface charge density 1 . The plastic is then broken into a large piece with surface charge density 2 and a small piece with surface charge density 3 . Rank in order, from largest to smallest, the surface charge densities 1 to 3 .
