1 million atoms across the thickness of a hair (100 micro Meter)

Atomic number on the atomic scale (element table) is how many protons are in the nucleus
  (ex: carbon can have various neutrons and electrons, but MUST have 6 protons)

The E in Gauss’s law represents the total electric field at each point on the real or imaginary surface under consideration.

We will explore the surface integral (and the dot product & unit normal that appear inside it)

Simple electric field equations

and their corresponding graphics:

Vector DOT product

Terms:

Vector Magnitude (aka: length)

 dot product (aka “scalar product”)
