ActivPhysics

Simulation for question number 1 - 2:
This simulation shows the characteristics of electric charges.
Equal charges' electric field point away each other, while different charges' electric field point toward each others.

Simulation for question number 2:
Representing the electric field: electric fields come from the positive charges that move into a negative charge.


Simulation for question number 3-5:
Uniform field simulation -electric field in every region between the two plates is the same.

Spreadsheet

Finding the magnitude of electric field in 4 different points. formula E = kq/(r*r).

E-Field Vectors from a Uniformly Charged Rod

The total charge of this rod is Q = 5x10^(-8). We divided the charge into 10 equal parts, so Q = 5x10^(-9). Each charges will produce different electric field in point P because the distance between point P and 10 charges are different.
