Notes:  

Coulombs: values of all vectors have  to cancel each other out.  

Gauss’s: look for symmetrical place  of charge to use gauss’s law. Electric  

Solid Insulator charge = Q

                    A                +        A and C: E = tFG                     B                +         B:   E = 0                      C If you want to learn more check out Matter can be classified into how many elements?

Field vector doesn’t need to come  out in some direction, but will if area  is symmetrical. ~~~For line and  plane, draw cylinder around ~~~
