Electric Fields

The above picture is a list that describes electric fields.

This picture shows instructions on what to do in VPython in order to recreate that picture with vectors representing the electric field.

The above picture shows my modification to the code provided by Professor Mason. This program illustrates the 3 dimensional electric field (the arrows) created by the positive charge at the center.

The picture of the graph above is what I assumed the code provided by Professor mason would result in. I was incorrect though because I forgot that the number placed in the X component does not point to a location, but in fact is a direction and length. The picture should have shows all arrows pointing to the right.

The above picture shows the calculations for finding the x and y components of an electric field vector using the formula (kq/r^3)x and (kq/r^3)y. The picture of this picture shows the magnitude of the electric field vector.

Here we found the total electric field vector for the point on the y axis. Since the charges are equal and opposite they cancel out making the total electric field vector a 0 vector.

The above picture shows our excel file which has a list of radii, their corresponding energy fields with the given k and q, then the sum of those energy fields on the bottom.

This picture is similar to the one above except that it also shows the electric field in the Y and X axes, and their summations at the bottom. Since the point that we were checking was at the center of a horizontal pole below it, the electric field cancels out.

This picture shows the integral to find the electric field across a line.
