Electric Fields

Electric fields are dependant on the magnitude of the charge producing the field, the distance of the charge from a test charge, and they can produce forces on other electrically charged objects.

An electric field vector can be calculated by multiplying the direction of the position vector by the limit of the magnitude of the electric field as test charge goes to zero.

The steps listed are an algorithm for a computer program to calculate an electric field.

Our assumption of what the given code will produce

The total electric field at point 1 is 8*10^10 N/C.

In order to calculate the total electric field at point 2, we had to find the x and y components of each of the fields produced by the two charges, and add them together. Here is the field caused charge 2.

Here is the field caused by charge one. As you can see, the vector E, total was calculated by adding each of the two components.

Integration of a charge uniformally distributed across a line to find the total electric field.
